I think I’ve found a bug that also shows itself in your VRExpansionTemplate. If I enable the ‘UsePhysicalGraspingHands’ boolean for physical hands in the Vive_PawnCharacter and then pick up the gun with the hand sockets and hold it with both hands, so both are in their socketed positions, I get warning messages in the log: “Invalid Simulate Options: Body (GraspingHand_C_1.SkeletalMeshComponent0 MannequinHand_Right) is set to simulate physics but Collision Enabled is incompatible”
I’ve tried to track it down, but I’m no Yoda. 4.27.
The warning also displays if I enable physical grasping hands from the wall display dropdown box, too.
