That's very strange, I've never heard about that issue. Well, the only thing that I could think of is that make sure that the 3d model you're about to voxelize is correctly exported to an OBJ before importing it into Qubicle.
You can learn more about it here: http://minddesk.com/learn/article.php?id=80
I suggest also reading everything in the "Learn" database, like read everything (it won't take that long). You can find the main database here: http://www.minddesk.com/learn/
If you have any other problems, that cant be resolved by reading the "Learn" database or cant be solved on this forum, then I suggest contacting the developer here: http://www.minddesk.com/contact.php
Good luck! I hope I helped: slight_smile:
