I am currently trying to create a texture, with holes in, or a transparent one. Something visible, yet see through. But, the method is yet eluding me, after fiddling with PSP8 images and shaders i'm still having no luck
Create an alpha channel for your texture, color the transparent parts black and the solid parts white (in the alpha channel), save it as a 32 bit tga, use this shader:
textures/yourfolder/yourtexture
{
qer_keyword metal
surfaceparm metal
surfaceparm trans
cull none
{
map textures/yourfolder/yourtexture.tga
depthWrite
alphaFunc GE128
nextbundle
map $lightmap
rgbgen lightingDiffuse
}
}
