It is a well kown problem for Poser figures.
Arms-upper shoulder.

I model my arms lowered just for that purpose.

You can model them perfectly in the "T" Pose, but normal people do not walk around in that "T" pose... :-)

That is why I allways build in "T", but then correct at the lowered position.

I want my arms to look correct in a lowered position.
