I have an old FBX model. It has pieces misaligned when brought into Poser. I thought I could fix the misaligments then and then save it as a Prop.

The problem is the thing must have at least two hundred separate parts. Nice if I was going to blow it up but as it stands now, I can't turn the whole thing one way or another. Retexturing must also be done piece by painstaking piece. Is there something I have to do to prepare FBX for use in Poser? Is there a way I can remap it so I can add a name to it? I have attached a screenshot.
