Re: [Opensg-users] using more than one texture at a time...

[Matthias B. <mb...@un...>]

Hi Enrico, hi Gerrit,


isn't there an alternative by using ChunkMaterials (which would be needed 
anyway for the shaders)...?
I thought about building your Chunks, I guess in Enrico's case something 
like Vertex/FragmentProgramChunk and the TextureChunks (for cubemaps there 
exist a dedicated CubeTextureChunk).
Finally you put them all together in your material in the desired order 
(shaders, tex0, tex1 etc.) and apply that one material to the geometry...

Correct me if I'm wrong - but that's the way it works for me, though...;)

bw,
Matthias
