How do I create a light emitting texture?

[danrobjim]

Is there any way to create a light emitting texture?

Yup, you just hafta make a SHADER!

 

Involves surfaceparms and such... I'd attempt explain it, but frankly I don't know where to start. Try looking at some of the "skies" .shader files in your assets files and look at the light-emitting skies to get an idea.

It's

 

q3map_surfacelight #

 

line in the shader code where # is the number representing light intensity.

 

edit:

 

The simpelest light emitting shader might look like this:

 

textures/mymap/mytexture
{
       q3map_surfacelight 100
       q3map_nolightmap
        {
                 map textures/mymap/mytexture.tga
        }
}
