That is exactly how I would do it. Sorry I am lost here. Someone else
need to comment on that. Maybe you need to call some update function
of the Material or the Chunk in order to make the changes effective.
Maybe you also need a BlendChunk for rendering semitransparent objects.
Another possibility is to assemble your material based on ChunkMaterial
and just add the chunks you require: TextureChunk, MaterialChunk etc.
That's how I do it in my implementation.
Manfred.
