Moho Animation Forum

Hi ALL! Hopefully someone can help! I'm on AS Pro 6. I create pics in Photoshop and export using the AS script (they become PNG files) into AS. While in pieces, I rig, set to region bone, set each bone strength and re-orient in the "stage" frame. However once I move each layer...they begin to stretch. A full arm rotation from a shoulder bone actually ELONGATES the hand and arm. Help please...it's destroying the animation.
