My attempt to copy what LCBoliou did in truespace. Sphere and the walls are just the glass shader with a color added. Light is white, and the polygon is default. First three object set to cast no shadows and receive no shadows. Line cone off and then on. Below it is a Vue version of the same thing, which makes me wonder how I can work around this. MarkBremmer: That's getting most of my concerns, I'm just worried about what would happen when I get to a complex image with a transition between indoor and outdoor within it - with something looking into or out of a window.

Truth has no value without backing by unfounded belief.
