For anyone else working with Sprite Kit and physics bodies in AR space, can you turn physics on and tell me if you're seeing this issue. Physics bodies that are behind the user, are mirrored in front of the user. This is only the physics body that is appearing though, not the SKSpriteNode (or its children). So its basically invisible, but the physics body is there and reacting to everything.
I've been working on a project for a couple months and just started noticing this in Beta 9, and I definitely would have spotted this bug before. So I think its new to Beta 9.
Can anyone else verify this?
