hm, you should be able to just increase that number in OSGTextureChunk.h
(you are using OpenSG 1.x, right?) and recompile. That should allow you
to add more textures to a ChunkMaterial or more precisely the State
object it holds internally. Every State you create will have that many
slots for textures on it, so don't set it to some huge number, because
that will just waste memory (something like 32, if the hardware supports
that many textures should be ok though).
I'm not sure if we want to do this change for everyone though. How many
textures can hardware handle nowadays?
Cheers,
Carsten
