So I tested my game in the VR preview window and it works perfectly I can see my tracked controllers no issues then when I package the game, no controllers I can’t see them at all. I think maybe they have turned off but no as soon as I go into Steam VR I can see them again.
Did you add mesh components to the motioncontroller components of an instanced pawn/playercontroller within your scene? If you haven’t yet, make sure the actually classes are assigning mesh components and that your default pawn/playercontrollers are assigned to those classes. If you change maps and use the VR preview, do you have the same issue? If so, then this is likely what you have to do.
