Mixamo Animation Retargeting

[twalk1776]

Hi! Thanks a lot

I think that unfortunately this is the default behavior in UE4 when you do animation retargeting: if the target skeleton doesn’t have all the bones of the source animation, such bones are ignored (see for example this answer - the question is similar to your: Extra bone but still can use the main skeleton - Character & Animation - Epic Developer Community Forums). The reason is simple: as you are transferring informations to a new mesh, the system doesn’t know how to automatically add such bones and - more difficult - how to properly skin them on the new skeletal mesh.

If you want to apply such animations to the UE4 mannequin, you have to add and skin such bones to the UE4 skeleton and skeletal mesh before, then apply the retargetings. Unfortunately it’s not a quick task. But maybe there is some other solution that I’m not thinking about.

Ohh I just saw this post… Hmm seems like an issue UE4 should have figured out, but I suppose this solution will have to do…
