1. I use 3DS Max, because Zmodeler is difficult to me beleive it or not, the only thing I use Zmodeler for is Scaling the model and UV Mapping. 2. Buildings are easier, vehicles are not that hard once you get the hang of it, the worst part is UV Mapping. 3. You can go to www.turbosquid.com, they have some low-poly and high-poly models. (but they're not free) I meant how is EMCUnits mod going, but sure, okay. Lol
