Yup, it is best to export with wavefront object format just as Poppi said. I have never had that problem doing that. How strange, do a test with the standard P4-women. Create a new project, and load P4-women ONLY, "JUST ONE FIGURE". Then export her to wavefront, and import it into Bryce and see what happens. You will probably see that it imports just fine. Next do the same thing with a new project, but use the figure you have been using,"Just by itself", and see if it imports any differently into Bryce. See if you can narrowing it down to this figure your using only.
