visible - invisible

[Rawing]

i'm trying to make a klesk-skin: first it should be invisible but then it has to become visible.

models/players/klesk/nightmare
{
{
map models/players/klesk/[invisible picture here]
blendfunc blend
rgbgen lightingDiffuse
}
{
map models/players/klesk/nightmare.tga
blendfunc GL_ONE GL_ZERO
rgbGen identity
rgbGen wave triangle .5 1 0 .5
}
}
doesn't work. i tried something like 30 different methods of making it invisible, but nothing worked. help please.

I suppose by invisible, you mean just the second stage only and not the entire shader?

rgbGen modulates vertex colours. It doesn't have anything to do with transparency. I think you want to use alphaGen wave.

Also, you wouldn't have two rgbGen values anyway. Use one or the other, not both. You don't need to specify blendFunc GL_ONE GL_ZERO since that is essentially, no blending at all.

so, how would the correct version of the shader look like?

I'm not going to write it for you otherwise you won't learn anything. But I already told you everything you need to do to make the shader work.

LOL?? if i would be able to write it myself, i wouldn't have asked how it would look like.
