VRM Retargetter issue

:police_car_light: Can someone help with VRM models in 5.5 and using VRM4U plugin :police_car_light:

I am having couple of issues.

1 - Leg IK seems messed up on Model A

2 - [ FIXED ] By default model B is been rotated to 180 on Z (Exported via VRoid Studio) How can I fix this ? In Char BP if Skeletal Mesh is being rotated it’s not working on the go. Seems it was pivot point issue. How can i deal with this ?

Thanks in advance
