I looked into it, it is fixable, but not BP only. You are correct though, default implementation only simulating objects collide with an attached actor. I’m mulling over which would be the simplest fix out of a few options.
I don’t think Epic is going to “fix” it by the way, as far as they are concerned for standard games it is the correct behavior. I’m pretty sure it will require a new derived pawn with some overridden functions to do correctly with VR. They might do that themselves in the future but for right now it appears to be on us.
