texture question - can i ...

(IndyJones) #1

is it possible to set in shader (or somewhere) a specific texture (to be exact 64x64 tga picture, pure white color, nothing else) to don’t get a light? ie when you compile with -meta, all textures are bright and don’t have any shadow. kinda hard to explain with my english, but i hope someone understand what i mean :wink:

I think you mean a texture without a lightmap. It must be possible

It’s been a looooong time since I looked at any q3 engine shaders, I refer you to the manual:

http://www.heppler.com/shader/shader/index.html

There’s a number of ways you can do it as I recall a blendfunc add, will do it although it probably rely on an additional base stage (which makes it inefficient). The glowey windows in goldrush use the same technique.

Or you can mess with RgbGen, in which you can set the colour and as I recall it’s overbright factor.

Sorry this is so vague, and probably of no use :slight_smile:
RTFM! :tongue:

Here we go Indy:


textures/paz/onlywhite
{
	qer_editorimage  textures/paz/onlywhite.tga
	surfaceparm nolightmap
	surfaceparm nomarks
	{
		map textures/paz/onlywhite.tga
		rgbGen identity
	}
}
