UE 5.4 Animation Retargeter Issue



I am having this retargeter issue in UE 5.4.
It was working fine in UE 5.3, but in 5.4 it’s having issues. I don’t know why I tried manual retargeting as well as auto retargeting, which is the 5.4 new feature. still having issues.

I already see two issues:

  1. The default poses do not match. They absolutely must, or you’re going to have accuracy issues.
  2. There are different spine bone counts in the two skeletons. (Which you try to address manually).

For “2”, I would use Unreal’s default retargeter:

Copy and retarget all animations for the UE4 skeleton. Then I would set the UE4 skeleton as compatible to your “Pink Guy’s” skeleton (found under Retarget Manager) :

Now your Pink guy can use the retargeted animations of the UE4 skeleton (and vice-versa, if you set it up that way).

It didnt worked.

I know this might be a simplistic question, but did you try using the new 5.4 retargetting method, which is 100 times easier then the 5.3 method ? If yes, what were the results ?

The 5.3 method requires so many steps in which if you don’t follow them properly, can cause this deformity that is displayed in your video example.

I tried it but it also didnt worked.

For me worked to switch from movable to static and than suddenly the actor was on right place…
