**odf**,

Perhaps the bending of the Thumb3 actor in the 123 figure could be improved. The orientation does not seem correctly aligned with the geometry, and this leads to the joints bending in an unexpected, and awkward way, looking dislocated.

I found that the following values in the Thumb3 seemed to improve the situation, though I have only done a quick test so far.

actor rThumb3:1
orientation 6 42.5 -38.241

actor lThumb3:1
orientation 6 -42.5 38.241

The Thumb2 actors also bend in an unexpected way, though it is less of a problem there, and perhaps it is necessary to maintain the current orientation in Thum2 for compatibility with the Thumb1 actor.
