How to fix animation retargeting issue?

I know there are posts about animation retargeting on the forum, and I’ve seen that this feature has been implemented, so I decided to run a test.

My process:

  1. Downloaded two characters from Mixamo, Michelle and Timmy, in T-Pose.
  2. Applied the Hip Hop Dancing animation (default parameters) to Michelle, downloaded without skin.
  3. Imported the two models and the animation ( Import options: I unchecked all the checkboxes).
  4. Then, as described in the documentation, I checked the T-pose of both models in Blender and found no obvious differences. However, the behavior in the engine is exactly as shown in my screenshot: the arm-crossing issue I often encountered in Unreal. But in the Flax engine, I don’t know where to start to solve it.


Yeah, retargetting doesn’t work 100% times. If we won’t be able to make it work in such case we could add option to manually rotate/scale specific bones so manual retargetting could be possible to fix such arm issues.

Please tell me how to fix this problem. Thank you very much.
