Another work around, depending on your situation, might be to render your bryce animation first, then import it into poser before setting up the poser animation. I know this works on the Mac. If you judiciously stroyboard ahead of time it would make this technique easier. The advantage to this is that you can set up keyframes right over the Bryce movie, making synching a little easier. Now if you Have to have the character(s) walk behind a brycy object, you will need to import that object into Poser, which might be problematic depending on the situation. In that case you could do a seperate Bryce animation with the solo renderer and use Premier to composite it after the initial Bryce movie in Poser rendering.
