Hi guys, first time posting here. I haven't even really been doing anything with Poser lately, but I've been following this project from the shadows almost since it started.  

I was poking around with the sunsky light for an interior scene (which is a WIP, as evidenced by the mesh anomalies and lack of textures) in the attached image. I think it came out fairly well for just a lighting test.

 

I don't remember reading any more info on light portals here after its first mention, so I cheated a little bit by seeing what Blender does for them. It would seem that the only edit needed is to change the mesh's "Shape" tag(?) so it reads "PortalShape" instead. I don't think the UV section isneeded for portals, so that can probably be taken out as well if you want.

 

Oh, and thanks for doing all you've done LuxPose team!
