I just tried this with UE 5.3.2 and by adding the bones, fixing the skeleton, adding a IK retargeter, retargeting, and following the steps I was able to get good animations. However, the Animation Blueprint still didn’t move the feet. The animations when played individually worked, but the overall didn’t. I rebuilt the Animation Blueprint and that worked.
I used this video to rebuild it: https://www.youtube.com/watch?v=TE-SsP3pigs
Thank you all for the amazing help. It would be nice if the Assetsville folks would update their stuff to work more out of the box so us noobs would have a bit easier time.
