Okay, to the first question. Nope. the .br4 or .br5 format is unique for some reason; the only meshes that will export are the terrains, which, I gather, is because of their fractal nature. On the second, it youre lucky enough to be on a PC, there are a couple of programs out there that will allow you to import Poser animations. One is Susannah; theres a link further in the threads where to find it. If youre on a Mac, it has to be done manually with the Poser figure exported in pieces (not grouped; you cannot ungroup it in Bryce) and with a lot of preplanning.
