I was wondering if there is a place where one could get some already built cars or objects and such for compositing practice? I thought I was reading a thread a while back of a scene someone had designed in 3d and did a matte painting for but then brought in a stock 3d car to put in their scene without having to sit and model it. Any websites or anything to get this kind of stuff? Thanks
Turbosquid.com - this site has a search engine that finds just about everything out there, free or not. I believe you have to get a free membership before you can download. Just do a search and filter in the free stuff.
As you probably know, many of the "free" models don't have texture maps, or are low polygon versions, or are just badly modeled. There are some truly great models out there for pretty cheap. Do a Turbosquid search after you've looked at the free stuff, and check out the inexpensive stuff; you'll find a wealth of really well-made stuff. Good luck.
