用了外国一老哥给的方法:
Quit the game and open this file with a text editor.
C:\Users\<User Name>\AppData\Local\LF\Saved\Config\WindowsNoEditor\Engine.ini
Add this line:
[/script/engine.renderersettings]
And then below that line, add one or a combination of these with a higher value (the values listed below are the default values):
Gamma=2.2
r.TonemapperGamma=0
r.SkylightIntensityMultiplier=1
Explanation:
Gamma is the same Gamma variable that you see in the in-game settings. The Devs limit the upper bound to 3.5 by deliberately design a slider in the UI, but this variable actually can go higher than 3.5 (the devs set the upper bound of the slider to 5.0 when the game 1st came out in 2020). This value affects both the 3D scene and the 2D UI.
r.TonemapperGamma only affects the gamma in the 3D scene (not the 2D UI).
r.SkylightIntensityMultiplier can be positive or negative. This Sky Light affects some 3D objects (not the 2D UI). What objects are affected is defined by the devs. The Sky Light in the official game has a cyan tint, whereas in the beta (2.0.0.0 alpha), the Sky Light's color is almost white.
Example:
If you're playing the official game, try this (r.TonemapperGamma and r.SkylightIntensityMultiplier are unchanged):
[/script/engine.renderersettings]
Gamma=5
If you're playing the beta, try this (Gamma and r.TonemapperGamma are unchanged):
[/script/engine.renderersettings]
r.SkylightIntensityMultiplier=4
Edit:
For v2.0.0.17, instead of [/script/engine.renderersettings], use [SystemSettings].
Example:
[SystemSettings]
r.SkylightIntensityMultiplier=4
