I have two hand bones on a character that are meant to do the same animations, but on different sides of the character (left hand and right hand). This is on Blender 2.92.
I've gone ahead and animated from the side, before realising I've only animated one hand. I did not have the other bone rig selected, so the other hand missed out on getting the keyframes.
I would like to copy over the animation keyframes from the left hand over to the right hand, with little to no re-work needed.
What I've tried:
I've tried to copy and paste the keyframes from the animated left hand to the non-animated right hand. It however, does not seem to work.
If the hands are holding something, the alternative would be to make the right hand a child of whatever the left hand is holding via a bone constraint. I'm not seeking to do this though, I would like to have the keyframes available for both for tweaking down the line without messy constraints logic.
