Quote - have to admit I like MD but have they changed there rules on obj export??

Indeed there have been some changes in MD's stance on .obj files.

The license agreement for MD4 says for the Personal License:

Quote - Licensee may sell or distribute its original works and their derivatives in any file formats and Licensor acknowledges that it has no right, title, or interest in and to any such original works and their derivatives.

To my reading this says you can make your .obj's from the original patterns you make and do with them as you see fit.

A trial license, not surprising, does allow use for internal evaluation only.
