Re: Objects not cast a shadow option?
Hi Hans -- Unfortunately it does not look like this trick will work, although it was a good idea. I downloaded your box OBJ file, which has single-sided polygons & is transparent seen from inside the box, and opaque from the outside. I put this into a simple room in SweetHome and placed a light source inside the box then rendered the scene. No light escaped from inside the box. Moving the light source outside the box did, of course, illuminate the room.

Oh well, I can always find ways around the problem; as a last resort I can patch in a view of the exterior through the window in a Photoshop-type software after the initial render/save. The ability to set an object to not cast shadows during render would be a useful addition to the software though, if it could possibly be achieved.

Thanks for your help & suggestions ;)
