Well, whether they want to fix it or not makes no difference to me now.

Just wanted to add an update to what I posted above and point out that in fact even V4.2 has issues (very small ones) even though her mesh doesn't split.

In other words, the problem is down to both Poser and the Poser figures so I can't see it getting fixed any time soon.  I reported this plitting nonsense years ago yet it's still there even on brand new figures built since then.

They either need to fix it or continue to wave bye bye to potential content developers - lol

 

Wondering... did you export the mesh to get it into ZBrush? If you did, don't.  Either use GoZ or use the OBJ from the Runtime directly. Poser's OBJ export can sometimes act up.  As for the issue you're seeing in the arms when raised, I'm not seeing it on my end but If you can send me a zip of the PZ3, I'd like to see what you're seeing. 

Also,  and this is to everyone, if you have bugs be sure to file them with the company or at least contact Tech Support so that someone in-office is made aware of the problem.  I just happened to be here today and decided to give this thread a look. Not something I often do and not something I can garuntee I'll do again.
