I find that Maya is okay around the 150,000 poly mark for importing obj's.

Also can I just remark here: the original question with regard to getting a mesh into ZB is not a difficult task to find out for yourself in the first place. Its in the Zb help menu set plus the word import is in the tool menu...Im a real stickler for these types of questions because it clearly indicates the lack of enthusiasm to find out for yourself.

I think there was a thread with regard to this type of thing a while back. If its something totally unbeknown and alien fair enough because terminology can be diffferent in each package but the 'Import' command remains one of the most global of all in any of the software...

C'mon people engage brains!

Cheers
Jay
