Thanks so much tamte. That fixed it. This mirroring solution works for now.

Thanks for the info. I gave it a shot, and while the mirror pose SOP seemed to do the trick, for some reason it is breaking the skeleton animation when I put it back into the stream. The blue skeleton has the animation on the way into the rest of the network. I had used a stash pose higher up to store the original rest, and that works without issue. Not sure what breaks with this one. The white skeleton is the mirrored one I am storing, which is correct. But the main skeleton that comes out from the rig stash pose is the red one, which is the original rest_transform I extracted to mirror. I know that sounds a bit confusing, but maybe it makes sense.
Any more tips would be appreciated. Thanks

Loving the documentation for the retargeting tools. I am doing a full match setup between two skeletons that need a bit of rotation tweaks to get things oriented. Is there a way to mirror the tweak pose values from r <> l so I don't need to do each side manually?
It would need to properly invert some rotations, but not all rotations. Who doesn't love those little gotchas with rotations?
Any help would be greatly appreciated.
