Okay, I spoke too soon, now it seems every time I export an FBX all my morph categorisation gets screwed up and no morphs in the exported fbx file. grrr. I'm sure it's related though. There is no way Poser should be changing anything in the pz3 file just because I exported something as fbx though, surely? In fact, it doesn't' - it only changes what is currently in memory. If I reload/revert to saved then the categories of morphs are back. So it's "primarily" still a fail to export body morphs issue but likely due to inability to find files is my guess.
