@SirDustyDirks Glad to see your root motion is sorted out. You were correct to use the Root Motion Generator. The Pin Bone Op is used to pin auxiliary bones (like pinning IK bones to hands etc). You caught me before my morning coffee haha.
As for the scale issue in sequencer, I’m not really sure what is going on there. Can you verify that the scaling disappears when not running a retarget? It may be due to something else…
