I have not used Vue D'espirit. However, note that if you choose Bryce, there are a number of little oddities that must be taken care of during import, such as bits of clothing that are hidden in poser that must be deleted, setting transparencies manually, etc. that make it kind of a pain to import poser figures into Bryce. It can certainly be done of course; just be prepared to spend a some time doing it and learning how. There are a number of tutorials and freeware programs out there that are (or should be, I haven't actually tried several yet) extremely helpful in reducing the workload.
