Brushes limit for a mesh?

Hehehe :o) Well, that makes most thing clearer, thanks. Still makes me wonder though. I'm creating an editor, with the ability to save to .b3d. After getting a little frustrated the code archives ones didn't work, i set out to code my own. If i'm creating copies of brushes and textures every time i load a mesh, i guess that's the way it'll have to be.

Thanks again for your time with this. Most helpful and much appreciated. Cheers!
