i was wondering...
imagine a b&w striped moving shader,
the black ones are invisible.
is it possible to make the black parts possible to walk through,
and the white ones impossible?
I don't see how that can't be done, though I don't know much about shaders... Could you not make the black and white brushes seprate and then apply some clip shader to the white ones...or was that what you where talking about?
Or will a clip shader not move with the texture? Now I'm just confused.
You could do it that way, bork[e], but what the OP has in mind (if I'm not mistaken) is a single shader that has both solid and non-solid areas. Well, you can't do that.
make two same sized brushes. texture one face of each, one with black, the other white. now line the brushes up so the two textured faces sit on the same plane. voila.
but seriously, it can't be done. just make the solid brushes into func_trains and move them around.
I can't remember ever reading whether shader effects are synchronised between client and server, but I'm betting that they're not. Anyone know? In any event, don't func_trains get stuck on gibs/corpses/lint at every possible opportunity, meaning the system could lose synch and collapse at a moments notice? As with most gimmickry, this probably isn't such a good idea.
