Hello. I don’t have the skills to help you but I still want to share my experiences. I am facing a similar problem. I write about it (confusedly) here: Full IK Body in VR with Unreal Engine 5.0.3 . Basically I’m trying to use a full body avatar and implement the IK Rig so that my avatar’s legs fold when I crouch. In my opinion the problem I find is similar to yours and is related to the different sizes between VR camera, Character, etc … In my rig the control rigs of the feet remain at ground level while the bones of the feet obviously follows the skeleton. From the way the skeleton deforms I understand that my character is extremely high above ground level. I believe that the solution consists in resizing my avatar according to the coordinates of my HMD, that is: floor height of the HMD; distance between controllers. These parameters should be transferred to my Rig. In my opinion there are many problems due to the early adoption of the OpenXR runtime. The problem for someone who has just started using Unreal, like me, is that I don’t notice when I’m wrong and when the engine has bugs. I’ve been banging my head on this particular problem for at least ten days. Good luck! I wish there were more resources dedicated to VR. It is all extremely confusing. Unfortunately, we are still in its infancy, despite half a dozen years having passed since VR began to spread.
