Hi guys. Im a little stuck. Iv got a very heavy model and every single piece is its own subtool with its own polygroup.When i export from Z through the bridge my model comes in to keyshot but some parts are joined together sharing the same material. i cant seem to split them in keyshot. So How do i get it to export so that every subtool has its own material ? So i can drop mats on to say. the screws. the panels and such all individually ? Iv been messing for days now and im stumped. I got it to split better but there are still some parts joined ? can you help a fella out 
In the subtool pallet every single item has its own polygroup and its separate from its neighbour .
Think i got it… i think its the naming. i just seen duplicate names. Yep , never mind . i sussed it. it was the duplicate names. why zbrush does not auto rename newly made subtools from splits is beyond me. So if you dont rename keyshot clumps them all together as one subtool
