now, when there's animation on it, transform attributes already contain connections to transform attributes and you DON'T wantn to mess around with those directly. instead, create a temporary transform node (group), parent it to your object's parent, apply/delete constrain on that temp node, then set translate/rotate/scale channel values from temp node to your real object. delete temp node, and voila - you've set the values, but to the object itself it's just the same as animator setting T/R/S values manually. not a bullet proof method, but it works. -- http://groups.google.com/group/python_inside_maya
