Quote - sounds like the (usual) combination of unnecessarily high polycount and split vertices. as far as i know stonemasons work - actually the temple ruins only - he is doing not much better...although a talented artist! - sigh... if you think this particular particular project is worth the effort, you can try to split it. render props seperately and character seperately and put them together in your 2d app. with the shadow catcher/shadow only options in p6 this process is quite easy. A. ps - i don't think it is a good idea to keep this product covered. helps the merchant, but not your peers;)

 

if only I had a penny for everytime I was credited for making the Temple ruins :...they are made by The Hankster,not me
he's made some beautiful models...although those Temple ruins are insanely large in polycount for my liking..still a great looking model though.

something else to consider is the surface settings in what your rendering..does it use real reflection?,displacement?..,these things will also slow it down..
if the textures are too large you can also set the maximum texture size to something smaller
