Strange body distortion when using Metahumans with LiveLink Plugin in 5.5

[w.scharf]

I have been using the Optitrack to UE LiveLink workflow since the 5.0 version of the engine without any issues. I encountered strange body distortions that appeared in V2 of Optitrack's 5.4 Plugin update and are still present in the 5.5 version. I confirmed that this does not occur in 5.4 V1. I'm guessing it's due to the change from X-forward to Y-forward skeletons, but am not sure. I tried adjusting settings in the Metahuman BPs and swapping the skeleton from the "legacy" folder mentioned in the changelog, but had no luck fixing the issue. What steps should I take next?
