Bryce 5 Exporting Help


Just needing some help with exporting my Bryce 5 objects(rocks, houses, trees, etc.) to .obj or something similar so it can be used(or imported) in 3DS or some programs similar. Can anybody help me? I have tried to add the files into the create panel(triangle next to “Create”) and then export it as a similar extension. But all I got was exporting as .obp, which I cannot use in what im making. Any tips/hints?
