Noob's Rigging question.

I am a 3ds Max User, and use ZBrush mainly for Modelling and Texturing.
Since skinning in 3ds max using skin morph at the joint is really painful ( I suck at skinning anyway).
I decided to try rigging in ZBrush, pose several “Extreme Poses” to capture the infomation of mesh deforming within certain range of motion , then export them to 3ds Max for morphing.

After overcome the annoying ZSphere’s shrink bug in 3.1, I bind the Zsphere in my mesh.
But when I start to pose it into some “Extreme Pose”, it deforms strangely .
The Shoulder area (Red) just twist badly, elbow and knee (Blue) curl “smoothly” just as Max’s does.
Is there anyway to reduce these problems? Or should I just sculpt these poses manually ,then using 3d layer for morph?

that’s completley normal… in classical skinning you assign weight from some vertextes to a joint, so that they cannot be moved by another joint… i really ignore how is it done in zbrush… but i think that an additional zsphere in the chest and armpits should help
