Run your .obj files through STOMP

There is a short tutorial in this thread that shows how to use it. Very easy. Basically what it does is defrag the geometry file or something like that.

Also, by "smallest size", what do you mean?  If you use a really small bucket size it will take a very long time to render.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
