I'm so glad I do original designs mostly. Nevertheless, I lost some models on T3DS, models that I doubt would be copyrighted to start with. T3DS just swept away anything having a "company name".
All those car tinkerers must have been totally obliterated.
I can see the point in this though. T3DS probably want to profile themselves to the market segment that searches for non-branded material. Maybe it works. Maybe it doesn't.
