There is no program what will convert Bryce models that I'm aware of. However - and I'm not sure of this - DazStudio is supposed to be better integrated into Bryce in the most current versions. I'm not sure if there is a way to pass something from Bryce to DS though. If there were, you could get them out that way. Export from DS then to Poser. But since I don't use either program anymore,  I can't say for sure ;o).
