Right click the imported animation and select “Retarget Anim Asset” -> “Duplicate Anim Assets and Retarget”.
Uncheck the “Show Only Compatible Skeletons” if you have not setup rigs for both skeletons in the retarget manager (The bone names match the Paragon characters, so you dont need that at the moment)
Make sure “Convert Spaces to new Skeleton” is checked and click “Retarget”.
