It's probably some legal agreement E-on had to give to Curious Labs in order to be allowed to directly support the PZ3 format. The difference from your Poser Pro Pack to Lightwave example is that you're using a plug-in created by curious Labs, themselves, and they can do whatever they want with the format. If it had been the other way around, if the Lightwave people had come to Curious Labs and said they wanted to support the PZ3 format, then they might be in the same boat as E-On. If you're really interested in importing files from Poser to Vue, then exporting them back it Poser again, simply use OBJ format, which is supported for importing and exporting by both programs. -SMT

I'd rather stay in my lane than lay in my stain!
