The fact that the mesh was naturally laying flat, then rotated, created the issue, Billboard disregards any rotation.
The fix was to switch the mesh type to Quad (instead of Plane) since Quad naturally sits upright.
Also, "transparent" can now be changed at run-time. Desktop VR can handle transparency just fine, so it's nice to be able to provide that via a run-time check.
