A highly requested Feature that is now finally available in Version 2.0: The Full Body IK Avatar!
It is based on the default UE4 Mannequin Skeleton and will work with any other compatible Mesh.
In order to use the Full Body Avatar without any problems, you will first need to modify your original Skeletal Mesh!
To be exact, you will have to either remove or use a different material for the Head of it. Inside VR you don't want to be able to see the head and unwanted body parts.
After you have done that, you will simply need to import your modified Mesh and update the references on the Skeletal Mesh Components inside the VR Pawns.
A separate owner-no-see Skeletal Mesh Component is also available, which copies the Pose of the IK Avatar. This can be used to see your full body (with head) in a spectator camera or mirror.
