I'm not sure - I haven't used the import animation feature of Bryce 6 yet (I don't really do animations). Part of the problem is that Bryce doesn't remember changes made to the imported DAZ content after going back to D|S and reimporting - if you select teh dragon, in Frame 1, and Cop matrix, then go to D|S, then back to Bryce and pAste matrix you should avoid that part of the problem.
