This is what I get when I hit play in UE 5.6. What happened between 5.6 and 5.5 that is doing this?

I’m thinking maybe it has something to do with the Deformer Graph, but don’t even really know what the deformer graph does. The ML Deformer Nearest Neighbor Model is also deprecated. Am I supposed to use the ML Deformer Vertex Delta Model or ML Deformer Detail Pose Model? I don’t even know. The documentation is so bad and doesn’t cover any of this. It just says check on the “ML Deformer” plugin which doesn’t even exist. How is anyone supposed to use UE with such bad documentation?

I found some documentation that talks about the different models. In other words it explains what the ML Deformer Nearest Neighbor Model, ML Deformer Vertex Delta Model, but does not cover the ML Deformer Detail Pose Model.

Still haven’t got the ML working in 5.6 though.

I figured it out. I had to re-train the data and use a new Deformer Graph.
