Re: Multi-Displacement

[Philipp Oser <philipp.oeser(at)liga01.de>]

Hi everyone,
and thanx for the suggestions. Yep, that would work out. Though if there are also procedurals involved you'd have to color(/lightmap)-sample them (which is OK) to get them to work with the pushOP? I'll still see if I can get a shader to work for that. Anyone knows if there is a GENERAL problem with stacking up multiple displacements and considering the output of the first (including the changed normals) when applying the second? I'll give it a try...

Thanx again
Philipp

Oh, well there you go... that's the function I was talking about. I knew there was an easy solution to that problem.

yeah apply a texture map, then use it to drive a push operator,
i guess to get the tesselation advantages of displacement you could local subdivide the object excessively then run a polygon reduction on it?

Thanx Mathieu,
Yep, that's the one, though it's not behaving exactly as I thought it would. The iterative thing is nice, though. And makes me a bit more confident that something like that should be doable with multiple textures. Might look into writing a shader for that...Another thing would be to convert the first displacement to polygons (maybe with maya - can XSI do that somehow?) and do the second displacement on the new mesh...

Thanx a lot

Hi everyone,
is someone still have the Waterblue-Displacement-Shader lying around? Or has a working link? I'm trying to displace a geometry with multiple textures and each new one should consider the already displaced geometry and the new calculated normals. So if someone has a solution, help is greatly appreciated...
