Unreal Body Plugin
This first release of the plugin, targeted at Unreal Engine 4.26.1, features an easily integrated IKBody component which enables: Head movement, Leaning motions, Leg IK (to enable crouching), Arm-IK, basic walking animations and Finger IK.
While it does not require VRExpansion to function, a VRExapansion compatible pawn is included; and using the VRExpansion plugin & sample project is highly recommended. You can find it here: https://vreue4.com/
