Poser figures are only allowed to be distributed amongst licensed users of the Poser program. It is against the license agreement, and breaks copyright law, to export the figures from Poser and send the models (obj, 3ds, dxf, etc)to anyone who doesn't own Poser. The Poser figures you see being shared here are in PZ3 or CR2 format, which are exclusive to Poser. Only Poser users can open those files, so it is OK to distribute them. If you want to use any Poser figures in Bryce, you'll have to purchase a copy of Poser first. A Bryce preset file is a file format exclusive to Bryce. In the case of objects, the format is *.obp .
