Hi, It''s pretty easy to change gamma for textures and lightmaps, but how do I change the gamma for a build level (like in actual games via a slider)? Thanks, Crispy

I think there is an API function (Windows)
SetGammaRamp () or so.
but be careful, you can f*ck up your system-settings with this.
(like Quake 3 does if it crashes).
