Hard to say, but not necessarily, could be a problem. Transposer requires the runtime path.I don't use transposer because I don't use poser.There could be something in the pz3 not liked. I don't use those natively. I am not 100% sure a pz3 is for native, since I don't use them. There are some poser options that need to be turned off normally, I believe.Try a cr2, hr2 or pz2. I think you need to check uncompress geometry files first in poser, then disable use external binary morph targets.Of course, no dynamics. That should work w/ transposer.

No need to think outside the box....
