I've never looked at it that way, because you know, I have created all
the Lego(TM) pieces in my library using CSG... Having a bump_map might
actually work, but then I'd have the first piece in my library which
would be dependant on a seperate file... That is why I was looking for
help in this forum, to see if I could keep things in CSG... When that
doesn't work I'll give your (good!) idea a try!

Thanks Thorsten,
