I am.
Just for some clarification, my scene graph looks as follows:
mSceneRoot:[mSceneTransform]
|
mLightNode:[DirectionalLight]
|
mLightBeacon:[Transform]
|
mModelRoot
I use the navigator's getMatrix() as the transformation matrix for
mLightBeacon's transform. So, I don't think VRJuggler's presence should
matter, but I don't really know.
Thanks for the help,
Alan
