for max u should have obj importer (Obj to Max) , but its only work until max ver 5.1 , there is tutorial here how to instance material maps , so u can save your memory with only using 3 or 4 maps nice render depend on your light setting , i think u can do that in Firefly (p5 ), but max of course give you more superior light fx (especially in scene with a lot ambient ) and faster.. Cinema4d give me nice result too and faster if you not using their GI , and easy import process ( R.8) i hope this help
