JKA Shader Manual

[eezstreet]

The Q3 shader manual is the current resource we have for working with shaders.

So how about a shader manual that has some of the JKA specific keywords?

 

I will list the keywords here, and maybe someone can fill in the definitions?

Note that I am only pulling from the engine, q3map2_ or q3map_ definitions aren't included here (they're the same as in Q3)

 

• map

$whiteimage $lightmap

• clampmap
• animMap
• clampAnimMap
• oneshotAnimMap
• videoMap
• alphaFunc

• detail
• blendFunc

Great idea! Shaders manual will definetly be useful. It wont be ctrl + c ctrl + v and hope to get proper results anymore. It would be nice to have all available commands along with descriptions in one place.

Excluding the surface sprites stuff, what extra benefit does writing a shader manual give?

Just update the existing one?
