From UDN:

"In FBoneContainer::GetRetargetSourceCachedData, the source bones are assumed to relate to the same skeleton as the bone container, which is not the case when using a skeleton remapping to retarget between two different skeletons. This function needs to be updated to use the FSkeletonRemapping to calculate the bone indices correctly."

Steps to Reproduce

Playback animation that:

  1. Requires translation retargeting
  2. Uses skeleton remapping
  3. Is set to "Orient and Scale" translation mode

Expected Result:
The translation of the bones with "Orient and Scale" will remain as in the skeletal mesh.
Actual Result:
The translation of the bones will be set incorrectly.
