shader question

[Shad0wdane]

ok.. I put some snow in my map but all currently I think it looks kind of crappy due to the Overbright. As it just makes it look all white with no detail at all. I thought about just recommending turning it off but some people won't do this and anyway it makes the lighting look rather dull.

Is there something I can put in the shader to prevent the lighting showing overbright on it for just that shader??

Here are two screenshots, one with overbright turned on and off.

Try using rgbGen identityLighting

rgbGen identityLighting

Colors will be (1.0, 1.0, 1.0) if running without overbright bits (NT, Linux, windowed modes), or (0.5, 0.5, 0.5) if running with overbright. Overbright allows a greater color range at the expense of a loss of precision. Additive and blended stages will get this by default.

thanks that worked... still doesn't look quite how I want it. I'm probably going to tweak the texture a bit in photoshop to improve it.

Also, try the -gamma and -compensate switches. Something along the lines of -gamma 2 -compensate 4.

You know, forgive me for saying but Quake 3 sucks on bright lit textures. For things like Snow, its a never ending battle of "wshed out"ness. TBH dude, there is a simpel solution to this. Your map is looking good, but already I can tell it lacks atmosphere. Drop the lights down a bit, give it some nice shadows going on. That will not only help the visual theme of the map but also bring the brightness of that snow down a lot, making it a look a lot better.
