I have two problems.
#1: When using group instances, the lines that define the origin are huge and they clutter up the image. How do I turn them off? http://s9.postimg.org/eslz9x7f3/blender_issue.png
#2: When I set an object to be the child of a bone, the object immediately gets offset by the bone that it is a child of. How do I setup a rig so that I keep the offset of the object when it is initially assigned to a bone?
