Just to clarify "pieces" might be a problem. Have only experimented so much. That is a cr2, via native. I haven't worked with pz3 and I don't use poser so I can't say there isn't a difference in the way the program perceives the file. However, some settings in SSS are gonna be a problem, depending on what you are doing.

No need to think outside the box....
