Key points
- Most information and methods from the Unreal Engine 4 page are still mostly compatible with Unreal Engine 5.
Video
High dynamic range (HDR)
For a list of known games and their specifics, see Unreal Engine 4-5 games where HDR can be forced.
Unreal Engine 4 has had native HDR output support since version 4.14 and it can be forced in many games that don't officially support it with mixed results.
Until 5.1, HDR in DirectX 12 was broken out of the box,[citation needed] requiring the use of -dx11
launch argument to run games in DirectX 11.[Note 1]
Force the built-in HDR display output of the engine: |
---|
Engine.ini or GameUserSettings.ini to include the following lines or enforce the variables via UE4SS:
[SystemSettings] r.AllowHDR=1 r.HDR.EnableHDROutput=1 r.HDR.Display.OutputDevice=5 r.HDR.Display.ColorGamut=2 Recommended changes (optional): r.HDR.UI.CompositeMode=1 r.HDR.UI.Level=1.5 Notes

Other information
Unreal Engine 4/5 Scripting System
- UE4SS is a scripting system for UE4/UE5. Includes a console enabler script by default.
- While UE4SS has a high compatibility with most UE titles, certain games may also have customized the engine enough for UE4SS to no longer be compatible. Titles not supported by UE4SS may have support added by the UE4SS community, searching the GitHub Issues page may help to find UE4SS configs for unsupported games.

Notes

Enable developer console
- The developer console allows real-time adjustments through various Unreal Engine 4 console variables, along with being able to run debug commands like ToggleDebugCamera that enables a flycam mode. Most games ship with the console disabled, although often retains code related to it that allows for its reactivation through third-party DLL injection.
- Independent of custom game code - potential for reliability.
Enable console with a UE4SS script[1] |

Permanent console variable (cvar) changes
- Global list of all console variables available here.
- Like most engines that use console variables, Unreal Engine 5 has a config file that the variables' values are read from at startup.
- Unlike in most engines, the method it uses may not be obvious. Editing files such as
Scalability.ini
could result in entered values being ignored depending on the graphics settings. - Entering cvars into
Engine.ini
instead should ensure the value changes will take place.
Add cvar name/values to Engine.ini

Modding tools
- Customized versions of the Unreal Editor for creating custom maps and mods for select UE5 games can be found on the Epic Games Store.
