If I’m understanding you correctly the trace function (blueprint) would be part of the controller (red lined sphere used to grab stuff), I guess that would be part of the VR Simple Character?
Im a little new to UE4 so not sure where that VRSimpleCharacter Pawn is, I guess its hidden by default?
Any way I just made my second interaction using your system, its a primitive way of setting an object in place.
For example a key in a door or in my case a keycard in a terminal :0…
Like the idea of sockets will test that out at some point time.
Hmmmmm, what to make next… You made a utility belt I think (fat belly to stick stuff to :)? I will experiment with that.
