stper, You're more than likely right about that(Wasn't the F16 Lockheed or Boeing(sp?)?). Dudley would be the guy to ask about autos, though. I'm sure he's had to research this for his 3d models. I think also Sharen of SAMS3D ran into this on one of her models too in rgards to the soft drink, Coke. Aldaron ran into some sort of trouble on a scene he was going to do involving someone else's dragons. Although therer are some "educational" fair use exceptions to copyright laws, they do not extend to commercial endevours, I'm pretty sure. As a point of contrast, with U.S.patents, anyway you have to proove 18 percent differrence and a patent search is pretty expensive. It wouldn't hurt to do a little researce to see exactly how to go about it: Most counties in the U.S.(perhaps some other countries have something similar), have access to law libraries either in the courthouses themselves or as part of that county's public library system, and I'm sure a google of copyrighr law will turn up a bunch of links. In the admin fourums section of renderosity there's a 'copyright laws' forum. - TJ
