I have been looking for it and haven't found it yet, but I did come across some skinners that wanted to animate the k98 scope but didn't know the shader for it. So I'm sharing it:
textures/hud/kartop
{
surfaceparm nolightmap
nomipmaps
nopicmip
{
clampmap textures/hud/kartop.tga
blendFunc blend
alphaGen oneMinusVertex
rgbGen vertex
}
}
textures/hud/karbottom
{
surfaceparm nolightmap
nomipmaps
nopicmip
{
clampmap textures/hud/karbottom.tga
blendFunc blend
alphaGen oneMinusVertex
rgbGen vertex
}
}
