Thank you for your reply, but I have to admit that my programming skills are not enough to clearly understand what you are saying. Do you imply that a variable or a function is causing this? My project uses the default VR template (motion controller) but I have changed the way the VR pawn moves. It does not teleport but uses the thumbsticks to move in every direction. I am also using 6 identical landscapes 4033x4033 in one level without level streaming (I know that it is wrong but there is a reason for that). I am also using a pretty big light importance volume and about 40 post process volumes. Could these probably cause the problem?
