Alright I extracted the shader files from the jk2 pak files, and entered them into shaderlist.txt. Even then, the jk2 sky shaders didn't show. So I put this into skies.shader:
 
 
 textures/skies/yavin_up
 {
 qer_editorimage textures/skies/yavin_up.jpg
 surfaceparm sky
 surfaceparm noimpact
 surfaceparm nomarks
 surfaceparm metalsteps
 notc
 q3map_nolightmap
 skyParms textures/skies/yavin 512 -
 }
 
 
 After that it showed up in Q3Radiant as a shader. The others show, just not as shaders. So I apply the shader to the roof, then when I compile I get this:

 Its only when the shader is applied that I get this error. I'm just totally lost here. This is the first map I've ever made, for any game. The map itself is coming along fine and I know there's no problems with the map, its just the jk2 shaders I can't get working :confused: So what do ya know?
