This is expected as the VR template pawn will be using a different version of the PickUpActorInterface. What I wanted to test was whether it was the project settings or the project content causing the input issue. If the VR template pawn is receiving input and letting you move around then it sounds like it’s the VR weapons kit pawn or motion controllers that are causing the problem.
If you open up the MotionControllerPawn and BP_MotionController from the VR weapons kit, then hit Compile - are you receiving any errors inside these blueprints?
