Getting the Rotation of a TriMesh in an Animated Model

I have cause to get the rotation of a TriMesh/JointMesh in an animated model (MS3D).  I grab the TriMesh in the usual way and then seek to examine it so that I can base other nodes and their positions based on the location and rotation.  The location aspect is working fine; however the rotation (both local and world) continually return the same values, whether the TriMesh has moved/rotated per the animation or not.  I'm thinking that this must be a simple thing to do, as the scenegraph must be tracking these things for transformations, but I haven't found the way to access it yet.  A bit of help would be greatly appreciated! Thanks! :wink:
