Retarget animation deviated position

Hey guys I found a problem when I retarget my teammates’ made animation in the BIP skeleton to the original official mannequin skeleton. But one thing strange is after retarget the pelvis will go up a far distance from the root’s position, but another animation of that BIP skeleton will keep the same position after retargeted to the mannequin skeleton. And both of the animations originally keep the same position at the begining. How can I solved this problem?Thanks.


A bit of a late reply. But maybe it will help someone with the same problem in 4.21.1.

In the skeleton tree of the skeleton rightclick on options and check retargeting options. set the pelvis bone or equivalent to animation scaled. Hold ctrl + alt over the options for more information.
