Sharing animations.

I meant actually changing the scale of the bone in the mode in the 3d software that doesn’t set the scale to anything other than 1. In Blender this is done in edit mode (versus doing animation in pose mode). Thus in any animations the scale would still be 1. If you do this you can retarget animations from other rigs and they’ll still work. Even for crazy rigs, if you’ve got a mannequin pose in a pose asset (easily done by constraining the bones to a mannequin like rig and baking keyframes) you can end up with really good retargeting results. I’m guessing something like this is coming to UE4 later with the control rig sequence stuff which would give real time retargeting.
