"Thread : What is the simplest and easiest to use free renderer for MoI?"
Moi3d + Rhino + Hypershot + 2 Import steps = 200$$ + 1000$$ + min.200$$ = 1400$$ free renderer for MoI.(HiHi)

Yeah Moi3d import in hypershot and rendering is megasuper. (unfortunately without multi materials,when from Moi3d exports)
My favorite would be:
Moi3d + Hypershot + 1 Import step = 200$$ + 200$$ = 400$$ free renderer for MoI.
