Well first of all instances won't make any difference, Cinema will convert them to real geometry on converion to .obj 31722 isn't a particularly high count for a Poser model so there MAY be some geometry Poser doesn't like. Is that poly count of the Cinema file or the .obj file? If it's the Cinema file the use of instances will reduce the poly count considerably, the obj file may be MUCH higher. If you haven't already done it I would suggest importing the .obj file to Cinema and check the poly count again. However, since it won't import into Poser, Bryce or Vue there is probably either some bad geometry or a corrupt .obj file. If you can't figure it out you might want to send it to other modellers to see if they can find the problem. - Baz
