I'll look into this. That layer may be able to move forward. It's a long way back from the walls, but really there's no way of knowing how it will affect other things without trying. So might as well move it and see!

This would mean that people wouldn't be able to use it for an indoor/outdoor scene with the avatar inside and the window showing a view with the light used outside, of course. But as things are with the layer system, where most items end up placed is always some kind of compromise.
