I have searched the forums about it, and nothing relevant helped me. I am using a sky image from ydnar from his site, and here is the .shader I have:
textures/darksky/sd_darksky
{
nocompress
qer_editorimage textures/darksky/clouds-1.tga
q3map_lightrgb 0.8 0.9 1.0
q3map_sun 1 .96 .87 140 140 8
q3map_skylight 60 3
q3map_nofog
surfaceparm noimpact
surfaceparm nolightmap
surfaceparm nodlight
surfaceparm sky
Is this all I need? If not, what other parts of the shader do I need?
