[Radiance-general] Re: limited number of materials?

[Greg Ward]

For the record, there is no fixed limit to the number of materials,  
but if you are defining a different material per face,  you'll save a  
bit of time and memory by reusing the same material name.  This is  
what gensurf does when it defines a texture per face.  It avoids  
having a lot of names inserted into the hash table, and is more  
efficient.

Setting a palette is an excellent suggestion if that works for you.
