I wonder if there’s something simple I’m missing?
When I paste the reversed keyframes it copies the reversed values in all rotation channels even if originally just Z rotation was changed. Trying to troubleshoot I noticed it was only adding keyframes to the one channel, even though I have available as the keying set (after setting keyframes on everything with whole character), and autokeying turned on.
Once I manually hit I on the rotation, all channels get keys and the reversed pasting works.
Any idea on what I’m doing wrong?
Here are some screenshots of my settings:
