This page is for the UUU v4.x. If you are looking for the information for the free UUU v3.x, please go to the UUU v3 page on the Framed site
The UUU v4.x is a continuation of the core internals of the UUU v3, so it should work with all games the UUU v3 works with.
Please see for details how to get started and configure the UUU, General features and configuration. This guide will provide additional information for the controls / features specific for the UUU.
If you click Select and the game process isn't shown, even though you know it's running, it's likely the game runs as administator and you therefore have to run the UuuClient.exe also as administrator: right-click the UuuClient.exe and select 'Run as Administrator' or create a shortcut to the exe on your desktop, right-click it, select Properties and on the Shortcut tab, select Advanced..., then check the 'Run as Administrator' checkbox and click OK.
After you've successfully injected the dll, you'll get a series of notification windows in the top left corner of your game window which some info regarding what the UUU is doing. You can now switch to the Available features tab to see which features of the UUU are available with the game you're using it with.
Here, with Darksiders III as example game, all features are available.
The Dump object info button can be used to dump all active object names, their structure, functions, properties and the addresses in memory to a text file on disk. This feature is helpful for people who want to use cheat engine with the game at hand. See for more info the object dumping section below.
The Dump CVars button can be used to to dump all available cvars (console variables) and console commands, with their names, current value (in the case of cvars) and the help text associated with them, to a text file. This can help with tweaking games using the console. See for more info the cvar dumping section below.
It might be the UUU reports some elements aren't found while the game should be fully supported. This might be caused by assembly mismatches or the timing you injected the dll into the game process. If this happens try to inject the DLL at moment after you've loaded the level or after the game's menu has fully loaded.
Additionally to the normal configuration features, the UUU also has some additional configuration features:
The camera smoothing options are for when you want to record a video by flying through the game world and control the camera manually, so not through a camera path. Normally the input to the camera system will be used instantly and you see an effect immediately. However for videos it's often desired to have a smoother camera movement than what's needed when you position the camera for a shot.
The camera smoothing options will give you the ability to control how much of the input you're giving to the camera system is used in future frames so
it's creating a smoother experience; e.g. if you set the movement interpolation factor slider to
100 (default is
1), the input given to move the camera
forward is used over 100 frames and is slowly flowing away to 0 after you stop giving input to move forward.
Additionally if you first move forward and then move to the right, with the default setting of
1 the camera will first move forward and then immediately
move to the right. However with an interpolation factor of e.g.
100 it'll smoothly move to the right, more in a curve than straight away. This gives
smooth movement and rotations of the camera. For the Field of View there's also an interpolation factor, which can be used to smoothly zoom in/out so it's
less 'jerky' when you try to zoom in/out.
Try to combine the values for the smoothing factors with lower/higher values for movement and rotation speed to find the ideal setup for your recording. It's likely you want a higher interpolation factor for movement than for rotation and FoV.
The values are stored in the ini file for next time you start the client.
There are four camera shake factors you can configure to introduce camera shake for normal camera movement: Shake frequency for both movement and rotation, Shake movement strength and Shake rotation strength. For screenshots these factors are not interesting, but for hand-shot video, e.g. in combination with the interpolation factors, they can give a more natural appealing footage.
The Shake movement frequency and Shake rotation frequency control how fast the movement and rotation shake factors change direction. The higher the value the faster they'll 'shake'. The Shake movement strength controls the amount of movement shake will be added to the camera location in the up/down/left/right/front/back directions. The Shake rotation strength controls the amount of rotation shake will be added to the camera orientation in pitch/yaw/roll.
The strength will be applied equally among all directions and rotations. Try to experiment with which values work best for the speed you move your camera; a faster moving camera could use a camera shake with higher strengths than a slow moving camera. Good starting values are 1.5-2 for the frequencies and 0.4-0.5 for the strengths. Setting the sliders to 0 will remove all shake factors from the camera.
Camera paths have their own shake factors.
It might be the
~ key doesn't do anything, even though the console was created successfully by the dll. This might be caused because the game unbound the
~ key and therefore it's not possible to open the console. Additionally, you might be using a non-US keyboard, like an Azerty keyboard, and on those keyboards, the
~ key isn't above the TAB key and the engine won't recognize it.
To correct this, on the Configuration tab, the setting Key to open in-game console allows you to select from a small set of keys what to use to open the console. By default this is 'Tilde' (
~). Please select a key that's on your keyboard and which doesn't need Shift to be selected. E.g. on a French (Azerty) keyboard, the '$' key is a good choice, so choose in the drop down
Dollar ($) as console key.
It might be the game shows the menu when you alt-tab to another window. To prevent this, the UUU has two methods to block the notification to the game window that you've alt-tabbed away, and they're named Method A and Method B. In general, if your game doesn't show the menu when you alt-tab away to another window, leave this option to None. Method A uses a simple block mechanism inside the engine and keeps telling the game that it has the focus. It depends on the game if this works or not, but if it does, it likely doesn't lead to any glitches so first try this method.
Method B is a method that fairly often works, but also could lead to glitches in some games. If your game shows the menu when alt-tabbing away, and Method A doesn't fix it, try to use Method B.
These methods take effect as soon as you alt-tab back into the game and remove the menu manually by e.g. pressing ESC. Alt-tabbing away after that shouldn't show the menu.
By default the UUU selects the MatineeTimeDilation value in the engine for pause. This works for the majority of games. However sometimes this value doesn't work or gives odd results and instead it should choose the TimeDilation value to pause the game. This option allows you to change this manually: choose TimeDilation if the game doesn't work or behaves wrongly when pressing the PageDown key to pause the game.
By default the UUU pauses the engine with a (matinee) time dilation of 0.0. However some games crash with that value. In that case, please check this checkbox to make the UUU use the engine's default minimum value which is usually 0.0001. The UUU doesn't use this as the default because in some games a value of 0.0001 causes cloth/hair physics to go bezerk. And we can't have bezerk hair/clothing, it's not the 1990-ies anymore!
On the Configuration tab you'll find the Save configuration as default button. This button will save the current configuration (settings, key bindings, gamepad bindings, theme) as the default for the UUU, so it'll use these settings next time you use the UUU with a game you haven't used the UUU with before. It's not going to overwrite the settings for games you already have used with the UUU, as these have their own settings already set.
In-game, press the
~ key (it's the key above the
TAB key on your keyboard), or the key you configured if you're on a non-US keyboard.
This should give a small line at the bottom of the game screen in which you can type commands.
If you type the
~ again you'll get a larger console window which also shows the response of the game on your commands.
To do useful things like starting the debug camera, in a lot of games you first have to enable the cheats in the game. To do this, type
EnableCheats 1 in the console and hit
enter. After that, type
toggledebugcamera after you've loaded a level. This should give you the ability to move the camera around using your controller and WASD + mouse. This can be a good alternative for when the built-in camera of the UUU isn't available.
To go back to the game, type again
toggledebugcamera in the console or simply press cursor UP to go to a previous command. There are many commands to choose from. Not all of them work. E.g.
fly might say they're activated but chances are they're not doing anything. Commands like
fov 50 (to set the FoV to 50 degrees, default is likely 80),
pause (to toggle the pause of the game) and a lot of console variables do work.
For more information about tweaking UE4 games, please see the Tweaking Unreal Engine 4 Games guide on the Framed Screenshotting Community site for more info about what commands you could use to make the game look even better.
It might be the
~ key doesn't do anything, even though the console was created successfully by the dll. This might be caused because the game unbound the
~ key and therefore it's not possible to open the console. Additionally, you might be using a non-US keyboard, like an Azerty keyboard, and on those keyboards, the
~ key isn't above the TAB key and the engine won't recognize it.
To correct this by choosing a different key to open the console, please see the Configuration section above.
Alternatively, you can add a custom console key to the game's ini file. This doesn't always work, but it's worth a try if you want to use another key than is available in the menu. Follow these steps
- In explorer go to:
c:\users\<your username>\AppData\Local\<game name>\Saved\Config\WindowsNoEditor
- open Input.ini
- Add (pay attention to the empty line, that has to be there):
- Save and set the file to readonly. You can also set it to another key, e.g. K.
The Unreal Engine console supports copy / paste of text. This is a great help if you want to execute multiple commands and have to type them in every time.
Additionally, it supports multiple commands on the same line, where you separate the commands with the
| character. Combined with copy/paste you can
create long strings of commands in a text file and copy/paste them over to execute all the commands in one go.
showhud 0|fov 60|pause|toggledebugcamera|r.postprocessaaquality 2
This hides the hud, sets fov to 60, pauses the game, enables the debug camera and sets the AA to a lower quality so you don't have jitter blur.
The console also remembers a history of commands, and keeps the line with multiple concatenated commands as one line. To show the history, press the arrow-up key in the console.
The UUU offers some extra features for your game:
- Game speed
- Enabling this setting will allow you to control the game speed. This is similar to specifying
slomowith a value on the in-game console, e.g.
slomo 0.2will run the game at 20% of the full speed. It is only available if the Slomo pause is available (see Available features). A value of 1.0 is 'normal game speed' and a value of 0.0 is total pause.
- Npc animation speed
- Enabling this setting will allow you to control the animation speed of NPCs / other characters in the game. A low value will make them go very slowly, a high
value will make them go very fast. To pause the NPCs, press the NPC pause key, by default that's
END. Please see the note below about caveats.
- Player size
- Enabling this setting will allow you to shrink or enlarge your player's character in-game. Setting the slider all the way to the left (the minimum value) will make your character
(almost) disappear. Use this to hide your character. To make the setting take effect, the game has to receive input to move the character. If you have paused the game already,
Wor the left stick forward and after it the key for frameskip (default
- Existing game light intensity percentage (UE4.17+)
- Enabling this setting allows you to dim existing scene lights to the percentage you've specified. So if you set the slider to 10%, it'll dim all scene lights to 10% of their original intensity. This feature works in games using UE4.17+. This means that e.g. in Days Gone this feature won't have any effect. It might take a short period of time before the UUU has collected all lights in a scene so be patient. Some games bug with this feature and show only darkness immediately after enabling the toggle. The main purpose of this feature is to be able to add your own custom lighting to a scene using the Lights feature of the UUU.
- Toggle player visibility:
- This toggles the player's 'actor' pawn's visibility, as well as the visibility of directly attached 'actors' like weapons. It might be effects and other elements might not hide, but it depends on the game. The player isn't hidden for enemies, the visible representation (e.g. your character) isn't rendered
- Make player invulnerable
- This setting might not work in all games. It disables the flag that your character can receive damage, but some games have implemented this differently and in these games it has no effect. You can use this to create better action shots.
Npc animation speed might crash your game or cause enemies to disappear. It's key to first use the Npc animation speed before pausing Npc's as it might be the game you're using the UUU with can't deal with an animation speed of 0. It also might be the feature doesn't affect certain characters in your game. This is likely because these characters aren't deriving from the Unreal Engine's Pawn class.
If you pause NPCs and new NPCs are spawned, these aren't paused. This is because the UUU first grabs all existing NPCs and then pauses these. New NPCs spawned after that won't be affected.
This feature won't work in games which use Unreal Engine v4.16 or lower, so e.g. in Days Gone these features have no effect. Additionally, in games like Final Fantasy VII Remake, many of the features won't work because they're implemented with a custom pipeline by the developers of the game and these bypass the UE4 effects. Just try and experiment which feature has an effect in your game.
The post-processing tab offers a way to control a variety of post-processing effects of the engine. It depends on the game's engine version (the higher, the better), and if the game uses a given feature to make a setting have any effect. Below are the settings available to you through the UUU and what they mean.
The Depth of field settings work on the 'Diaphragm Depth of Field effect' of Unreal Engine, which is the default Depth of Field effect starting with UE4.24 and which has been used by games using older versions (e.g. Final Fantasy VII Remake). It therefore depends on whether the game uses this Depth of Field effect to have these settings have any effect in-game. Additionally, some games remove the Depth of Field effect from the camera's post processing pipeline during gameplay, like in Final Fantasy VII Remake, so enabling them in these cases also has no effect.
If the Depth of Field settings have no effect in your game, chances are it uses the older, inferior Circle Depth of Field effect of UE4 and you're better off using Reshade's Depth of Field
effects anyway, like my Cinematic DOF. To disable the depth of field effect of a game, use
r.depthoffieldquality 0 on the
- White balance
- This controls the white balance of the image. Lower values result in a more blue image, higher values result in a more yellow image.
- This controls the tint of the image. Lower values result in a more greener image, higher values result in a more redder image.
- Auto exposure bias
- This controls the logarithmic adjustment for the exposure. Only used if a tonemapper is specified. 0 means no adjustment, -1 means 2x darker, -2 means 4x darker, 1 means 2x brighter, 2 means 4x brighter etc.
- Color grading intensity
- This controls the color grading LUT intensity, if used by the game. 0 means no color grading, 1.0 means full color grading.
- Lens flare intensity
- This controls the intensity of the lens flares. 0 means no lens flares. The higher the value, the more prominent the lens flares.
- Tone Curve amount
- This controls the amount of tone curve to apply. 0 means no tone curve, 1.0 means the full tone curve is applied.
- Bloom dirt mask intensity
- This controls the intensity of the lens dirt texture. 0 means no lens dirt/smudges, the higher the value the more prominent the lens dirt/smudges will be, if set by the game.
- Bloom intensity
- This controls the intensity of the bloom. 0 means no bloom, the higher the value the more intense the bloom will be.
- Chromatic aberration intensity
- This controls the chromatic aberration (CA) that's visible. 0 means no CA is visible, the higher the value the more prominent the CA will be.
- Chromatic aberration start offset
- This controls where the chromatic aberration (CA) will start: 0 means at the edge of the screen (so it's not visible), 1 means at the center of the screen. Only useful if Chromatic aberration intensity is set to a value bigger than 0.
- Depth of field focal distance
- This controls the depth of field focal distance, in cm. Use the numeric textbox to control the max value of this slider. Only works if the game uses a recent UE4 version (v4.24+) or has enabled the Diaphragm DOF effect.
- Depth of field f-stop
- This controls the depth of field aperture / f-stop value. The lower, the more blur you'll see. 0 switches off the Depth of Field effect. Only works if the game uses a recent UE4 version (v4.24+) or has enabled the Diaphragm DOF effect.
- Depth of field blade curve min f-stop
- This controls the depth of field blade curve value. The lower, the more prominent the shutter blades will be in the highlights. Only works if the game uses a recent UE4 version (v4.24+) or has enabled the Diaphragm DOF effect.
- Depth of field shutter blade count
- This controls the number of blades used in the bokeh highlights. Requires focal distance / f-stop to be enabled. Only works if the game uses a recent UE4 version (v4.24+) or has enabled the Diaphragm DOF effect.
- Grain intensity
- This controls the amount of film grain visible in the image. 0 means no grain, 1 means maximum grain.
- Indirect lighting intensity
- This controls the indirect lighting contribution to the scene. 0 means no global illumation, the higher the value the more GI will contribute to the overall lighting.
- Screen space reflection quality
- This controls the screen space reflection quality of the scene. Only effective if the effect is used by the game.
- Screen space reflection intensity
- This controls the screen space reflection intensity of the image. Lower values make reflections less prominent. Only effective if the effect is used by the game.
- Screen space reflection max roughness
- This controls the maximum roughness used by the screen space reflection. Only effective if the effect is used by the game.
- Vignette intensity
- This controls the vignette intensity. 0 means no vignette, 1 means a heavy vignette.
Double clicking the slider's button will reset it to its default value.
To toggle all features on / off, use the Toggle all on / off buttons at the bottom.
The UUU has two ways to pause the game: using the normal UWorld::IsPaused hack, (
Numpad 0), and one using the slomo command code, (
You can use either one, if they're both available/found.
Numpad 0 is a hard-pause which could lead to TAA jitter in the scene.
You can remove that by stepping down the AA a bit, using the following command on the in-game console:
r.postprocessaaquality 2 in the console.
To set it back, use
r.postprocessaaquality 6. The downside of that is that cutscenes might play on and the lower quality AA might remove some effects.
The slomo based pause using
Page Down doesn't suffer from TAA jitter, and can pause most, if not all, cutscenes as well (except audio in some
situations). In general, if the latter is supported, you should use the slomo based pause.
If both don't work, you can try
pause on the in-game console.
pause isn't an official command but a lot of games support it in one way or the other.
Starting with v4.1, the UUU offers the ability to create an infinite number of custom lights in a UE4 game. If the feature is available in the game, you can use the Lights tab to create new SpotLights and PointLights and edit their characteristics. A SpotLight is a light which shines a cone of light in one direction and a PointLight is a light that shines light in all directions.
The screenshot below shows an example where two SpotLights have been created
The grid shows the following columns:
- Is Active
- This column shows which light is the 'active' light for keyboard shortcuts. The light which has 'True' in this column is affected when you press one of the keyboard shortcuts that work on an existing light, like attach to camera.
- Light Type
- The type of the light, be it SpotLight or PointLight
- Is Attached
- Each light which is attached to the camera has a toggle button shown in this column. You can use this toggle button to detach the light from the camera. When doing so and you left the option Preserve camera state when attaching a light checked, then the camera will move to its original position (unless the free camera isn't active).
- Is Enabled
- This column contains a toggle for each light to switch it off and on
- This column offers a color editor for quickly changing a light's color without going into the light editor.
Additional to these columns, the last column contains four buttons per light:
- This button will move the camera to the light and attach the light to the camera. This will mark the light as 'active'.
- This button will move the light to the camera and attach the light to the camera. This will mark the light as 'active'.
- This button will create a copy of the light at the position of the camera.
- This button opens the light in the Light Editor and marks it as 'active'.
The buttons that attach a light to the camera will preserve the original camera position, if the option Preserve camera state when attaching a light is checked. The camera will return to that position when you detach the light from the camera. Attaching a light to the camera gives fine-grained control how to position the light.
When you have a light attached to your camera and you move it around, it might be the engine will stop updating the light in the 3D world. To fix this, switch the light off and on again (yes, really) and the engine will restart rendering it. Use the toggle under Is Enabled for that.
At the bottom of the Lights tab the following options are available:
- New SpotLight
- Clicking this button will create a new SpotLight at the location and rotation of the camera using the default values.
- New PointLight
- Clicking this button will create a new PointLight at the location and rotation of the camera using the default values.
- Toggle All Lights On/Off
- This button will toggle all lights you've created on or off.
- Delete All Lights
- This button will delete all lights you've created. It'll ask for a confirmation first.
- Preserve camera state when attaching a light
- Checking this checkbox will perserve the camera position and rotation when you attach a light to the camera. It's then moved back to its original position when you detach a light.
When you're done with a scene and thus your lights are no longer of value, it's highly recommended to delete them. It might be the existing lights will keep the game from loading another level or might even crash.
When you create a new light and it doesn't seem to affect some elements in the world, e.g. your character is unaffected by it, please check the light channels
When you click the Edit Light button of a light in the Lights tab, it is opened in the Light Editor. The Light Editor looks like the following screenshot:
The Light Editor has many controls, which you can view by expanding the various parts, like Placement and Rotation, Shadows etc. The Light Editor remembers what you have expanded so next time you open a light in the Light Editor, you don't have to expand all groups again.
The Light Editor offers the features as available in UE 4.26. It might be your game is built with a (much) older UE 4 version, and therefore not all features will work. It goes too far to list for each feature when it's supported, so a bit of trial/error is required. The basic features like color, intensity, placement and the like are always supported.
The Light Editor offers several numeric textboxes like the x/y/z coordinates. To change these, click inside these textboxes and use your mousewheel to change these values quickly. Hold Shift while using the mousewheel to change the value with bigger steps, hold Control while using the mousewheel to change the value with small steps.
The Light Editor offers the following functionality:
X and Y are horizontal, so changing X and / or Y will move the light in a horizontally direction. The X and Y coordinate are relative to the world, not to the camera. Z is up, so making Z smaller will move the light down, making the value bigger will move the light up.
- This is the x coordinate of the location of the light.
- This is the y coordinate of the location of the light.
- This is the z coordinate of the location of the light. (Up)
The angles are in degrees, so 0 and 360 are the same position. If you move the slider of an angle to either the start or the end, you should continue on the other end of the slider. So moving the slider to 0 (the left edge, or start of the slider) makes you can't go any further as the slider stops at the left edge. To rotate the light further in the world, you should move the slider all the way to the right (360 degrees) and then slide the slider to the left.
- This is the angle to rotate the light up or down. 0 is straight down, 180 is straight up.
- This is the angle to rotate the light left or right.
- This is the angle to rotate the light along itself. This angle is usually 0, and only used if you use the source radius settings (further below), so you can rotate the reflection.
- This color editor allows you to edit the color of the light using HSV, HSL or RGB editors, whatever you prefer. See the Wikipedia article about what HSL and HSV means.
- When enabled allows you to specify the temperature of the light, from 1000 Kelvin to 15000 Kelvin. This is additionally to the light color and can change how a light's color will look. See the chart below what temperature does to a white light. It's recommended to first use the temperature slider to set your light's color, unless you're going for a light color that's not achievable with the temperature slider. The main reason for this is that temperature changes won't affect the luminosity of the light, while color changes do.
- The brightness of the light. The maximum value of this slider is controlled by the Intensity max value slider.
- Intensity max value
- The maximum value of the Intensity slider. To be able to have fine-grained control over the Intensity value, the maximum is configurable.
- Attenuation radius
- This slider controls how far in the world the light will affect geometry and models. The higher the value the more will be lit by the light.
- Volumetric scattering intensity
- This is the amount the light affects the fog that's in the world. It might be this option doesn't do anything, because there's no fog volume in the game at the light's location.
- Cast shadows
- This checkbox toggles shadow rendering of the light. Off means no shadows at all.
- Cast deep shadows
- This checkbox toggles deep shadow rendering, which is used on some hair rendering techniques in UE4. Only present in newer engines and the game must use the hair rendering system of UE4.
- Cast raytraced shadows
- This checkbox toggles whether the shadows cast by the light are done by raytracing. This requires the game to have raytracing enabled, which is available in v4.25+.
- Cast volumetric shadows
- This checkbox toggles whether the light will cast volumetric shadows in fog volumes when the Volumetric scattering intensity is set to a value that makes the light show a light beam.
- Shadow bias
- This controls one of the two shadow bias values. In general: if the light is close to the object that's shadowed, setting this to a lower value gives sharper shadows and no banding. See the Unreal Engine documentation for more details
- Shadow slope bias
- This controls one of the two shadow bias values. See the Unreal Engine documentation for more details
- Shadow Resolution Scale
- Scales the resolution of shadowmaps used to shadow this light. By default shadowmap resolution is chosen based on screen size of the caster.
Constrained by the value set to
- Contact Shadow Length
- Length of screen space ray trace for sharp contact shadows. Zero is disabled. See the Unreal Engine documentation for more details
- Inner cone angle
- Sets the inner cone angle of the SpotLight, in degrees.
- Outer cone angle
- Sets the outer cone angle of the SpotLight, in degrees. Setting this value the same as the Inner cone angle gives a hard edge on the light's circle.
- Source radius:
- The radius of the light source shape. Mostly used for the reflection of the light itself
- Soft source radius
- The radius of the soft edge of the light source shape. Mostly used for the reflection of the light itself
- Source length
- The length of the light source shape. Mostly used for the reflection of the light itself
- Specular scale
- The scale of reflection of the light source shape. Setting this to 0 will mean the light isn't reflected at all.
- Affect dynamic indirect lighting
- Whether the light is added to the dynamic indirect light already in the scene
- Affect transluent lighting
- Whether the light is added to the light through transluent/ transparent objects.
- Affect global illumination
- Whether the light affects global illumination. Only in effect if the game uses a dynamic GI system.
- Affect reflection
- Whether the light is added to the reflections in surfaces. This isn't the light bulb itself, but the lit elements lit by the light.
Light channels are a way for UE4 to control which lights affect which objects in the world. A light that has only its Light channel 0 checkbox checked, won't affect any object in the world that's set to light channel 1 or 2. By default a light is placed in the light channel 0 (unless the game puts all lights in specific channels). E.g. if your light doesn't affect your character (e.g. in Darksiders III, the player's character is on Light channel 1), check the checkboxes of the other light channels to have the light affect the character.
Lighting is a complex topic and it can help to read a bit more about how lights work in UE4. The lights created by the UUU are movable lights and the documentation about movable lights in UE4 applies to these lights.
Starting in v4.5, the UUU offers the ability to move your player pawn, the in-game character when the camera is active. This can be particularly handy when you have paused the game but your character is not really in the right spot. This feature is only available when the camera is active so you can't use this to 'teleport' to another location on the map.
Player pawn movement and rotation has been implemented for mouse and gamepad. If you have the camera device set to gamepad, you can use the gamepad for moving/rotating the player pawn. If you have set the camera device to 'keyboard/mouse', you can use the mouse to move / rotate the player pawn. If you have set the camera device set to 'both' you can both use the mouse or gamepad to move / rotate the player pawn.
- It might be your player pawn moves but some part is stuck on the old location. This isn't solveable. After moving / rotating, press the Skip Frame button to quickly unpause/pause again.
- Some games don't let you rotate the player pawn when it's doing an animation. This isn't something the UUU can fix.
- Moving the player pawn when the game isn't paused will continue to apply physics on the character, so trying to move the character up or down likely won't work. Instead pause the game and then try to move the character up/down.
To enable move / rotate mode for gamepad, press the A button (or X on a Playstation controller) together with rotation left/right stick and/or using the triggers. Releasing the A button will make the gamepad move the camera again.
So e.g. to move your player pawn a bit to the left, hold A plus push the left stick to the left. To get fine-grained control over movement also press X (or
 on a Playstation controller) to slow the movement. To move the player pawn up or down use the left or right trigger. For rotations, instead of using the left stick, you use the right stick.
To enable move / rotate mode for mouse, press the Shift key on your keyboard together with moving your mouse and pressing no button or the left mouse button or the right mouse. Releasing the Shift key will make the mouse control the camera. The movement is the same as when controlling the camera with only the mouse. Holding Ctrl will give you fine grained control over the movement and rotation.
So like the example with Gamepad above, to move your player pawn a bit to the left, hold Shift while holding the left or right mouse button and move the mouse to the left.
Although the name suggests it's a universal unlocker that always works with any Unreal Engine 4 game, the reality is that developers sometimes change the game engine's code and the unlocker can't re-activate the console as essential functions aren't there anymore, or activate other features offered by the UUU. The list below are games which are known to work with the unlocker.
The Lights column mentions all games which have been verified that the custom lights work. It might very well be the lights work in many other games on this list. If you play one of these games and the lights work for these games but it's not marked as such on this list, please let me know.
If you're pausing with PageDown (slomo pause), and have motion blur enabled in the game's settings (or it's enabled by the game and you can't disable it in the game settings) you'll likely see motion blur streaks / blurry edges when moving the camera in games built with UE4.25 or higher. To disable this, please use
r.motionblurquality 0 on the console to disable motion blur. To enable it again specify a value higher than 0.

Additionally, most UE4 games on Itch.io are usable with the UUU.
The UUU can dump the object store with the memory locations, names, types, structure and more of all currently active engine objects a text file in the game folder, called
UUU_ObjectsDump.txt. To do that, on the Available features tab, click the Dump object info button. The memory addresses listed in the file differ per level and every time you run the game, so if you want to look up objects in-memory after you've loaded a new level, you have to dump the file again.
The UUU can dump cvars (console variables) and console commands with their name, current value, their type and help text to a text file. This text file will be placed in the game folder, called
UUU_CVarsDump.txt. Additionally, they're also written to a .json file in Json format, in the same folder, with the filename
UUU_CVarsDump.json. To dump the cvars, on the Available features tab, click the Dump CVars button. This dump will not only include all default UE4 cvars and console commands but also custom ones added by the game developer.
After you've dumped the cvars to a file, open it in notepad or other text editor. For a particular cvar, the dumped information in the text file looks like this:
foliage.LODDistanceScale | Float | 1.000000 | 0x0 (SetByConstructor) Scale factor for the distance used in computing LOD for foliage.
This tells you: the variable
foliage.LODDistanceScale is a floating point variable, has currently the value
1.0, has no special flags, and
has as help text Scale factor for the distance used in computing LOD for foliage. See for more information how to read and change console variables
Opening the in-game console.
When you dump the cvars, the UUU will reset flags that prohibit you from executing certain commands and setting certain cvars which set to readonly or are cheats. This doesn't mean they'll work or have any effect (as that depends on the final engine code being included in the game), but at least you can change their value and execute these commands.
Not all information is available in every game: help texts and flags are included when the game uses UE4.19 or newer. The current value and type are included when the game uses UE4.24 or newer.
When you create a Camera path, each node records the camera location, orientation and field of view. Additionally, the post processing settings: Auto exposure bias, Depth of field focal distance, Depth of field f-stop and Vignette intensity are recorded as well.
After you've enabled the camera (default with
Insert), you can store the current camera state in three slots. The camera state is the current location,
the orientation/rotation of the camera and the FoV, as well as other information recorded in camera path nodes, as the system uses camera path nodes under the hood.
By default you save the camera state by using
F1 for saving the current camera state in slot 1,
F2 for saving the current camera state in slot 2 and
F3 for saving the current camera state in slot 3. To restore the camera state to a saved state, press
F1 to restore the camera to the state saved
in slot 1, press
F2 to restore the camera to the state saved in slot 2 and, press
F3 to restore the camera to the state saved
in slot 3. These keys are configurable in the keybindings tab.
When you disable the camera again, the saved states are lost. If you want to preserve game states after you disabled the camera (e.g. you want to move the character a bit, and then enable the camera again), use a camera path and add the camera states you want to save as nodes. Camera paths are preserved after you disable the camera.
The default photomode mod controls are listed below. It depends on the Camera control device setting on the Configuration tab whether the device (e.g. mouse or gamepad) can control the camera.
When moving the mouse:
- No mouse buttons pressed: rotate the camera
- Left button pressed: move camera up / down / left / right
- Right button pressed: move camera forward / backward / left / right
- Both left and right button pressed: tilt camera left / right
- Mousewheel: increase / decrease Field of View (FoV)
When you are holding
Ctrl, rotation/movement is slower. When you are holding
Alt, rotation/movement is faster.
When moving the mouse and holding
- No mouse buttons pressed: player pawn rotation left / right
- Left button pressed: move player pawn up / down / left / right
- Right button pressed: move player pawn forward / backward / left / right
