You can import them into Bryce using at least 2 addon packages but they're both a heck of a lot of work still. I have one called Susanna which imports multiple saved Poser OBJ's that are exported from poser then imported to Bryce. I still have yet to even try it. I can't recall what the other one was called but it cost more money than Susanna. Both were available when I first got into Bryce & Poser back in the lat 90's around 98'-99'.
