Flyguy, I like your stuff. Good work. Your texturing is top notch, though for your renderings, a little more time on the shaders would work, especially since the settings would carry over most of the time. Monokote, is a little more glossy than that, though Ultracoke can be a little flatter, and the lack of shadows/reflections is giving the renders a super-flat work.
Not trying to bing you down, just a few pointers. I have not downloaded any of your stuff but I am sure it looks better in-game, as renders and game exports are two seperate things.
And I am not sure that the makers could take any legal action. You are making a 3D representation based on a real product. It would be like suing you for taking a picture or making a painting. They can not do that.
I do some part-time work for a small video game developer, we make a simulator and we have to copy real products all the time. We can not use the name of the actual design without proper licensing and permission, but for those that do not (a competitor has deals with some manufacturers, we have deals with others) then we copy the stuff and call it something else and they can not touch us. Yes, we have been threatened, but there is not jack they can do legally.
So as long as you do not call it a sky cutter, and you do not exactly mimick the paint job, then they have nothing to stand on. And even if you did, If you did not charge for it, then really there is still nothing they can do.
