Wasn't "The Girl" posed with the arms down and twisted out? This would certainly cause problems with costumes, but mainly because of the twist out. My workflow doesn't suggest that it would be more difficult making a costume with arms down at 45 degrees. Modo has lots of action centers to chose from and you can set workplanes to selections. As for morphs, I don't understand why these would be troublesome. The arms would be closer to the body, but you could still get at them. I've managed tighter poses in Zbrush. It's possible that the FBMs might even pose better.

On the other hand, this may just lead to another failure. This isn't an experiment to advance Poser. It's an experiment aimed at getting my figure's shoulders to bend properly. I'd use stone knives and bearskins if that would work.

A two part grouping for the palm is something that I've considered, having noticed how my hand actually bends.
