Hey Everyone, Happy New Year!
I wanted to see if you have seen this before. I have added an attachment to the RealityView as a child on an entity that has a Billboard component set on it. I wanted to create the effect that the attachment is offset by .5 meters from center and follows the device as you move around it. IT works great until you try click a button.
The attachment moves with the billboard, but the collision box around the attachment is not following it. If I position myself perfectly it works.
