For an all-around good rendering app, I'd recommend Carrara Pro (www.daz3d.com) - not only is it easy to learn, it'll also do your environments for you as well - something a lot of other mainstream rendering apps don't do.


Second to that, I'd recommend the very pricey Cinema 4D - C4D IMO imports MOI objects the best out of all the other apps I have (Softimage and Lightwave).

So if price isn't a problem, I'd recommend C4D for the quality of its MOI OBJ imports.

You can download the demos of both these apps and get a feel for what they can do for you - enjoy!
