Return Value
Success: TrueFailure: False
Remarks
Unlike regular billboards the billboard group does not always update the orientation of the billboards every frame.If you are a long distance away from the billboard group the camera needs to travel a significant distance before the
angle has changed enough to warrent an update of all of the billboards verticies to make them point to the camera once more.
You may want to force a refresh at some point with this call.
