'I can't help but wonder, mildly, if anyone has tried setting up any kind of light to cast a fraction of a shadow rather than making walls not cast shadows' Yep, I have. I have a room system available commercially and one lighting setup uses spots for the main lights, plus an infinite 'fill' light, set at a low intensity, but with shadows switched off. This fills in the whole room, but doesn't detract from the main spots. DrMax, Your room looks excellent. Re ernyoka's comment about material zones, she's referring to using the transparency values in poser. By setting a material to 100% transparency, you can make it invisible in a render. This has 2 disadvantages though. One is that the material may be shared by several parts of the prop or figure and maybe you don't want to make them all transparent. The other snag is that when a material is transparent, it still shows in the preview as tiny dots. Not a major problem, but it can be annoying. I find it better just to switch body parts/props off. There's one thing you may want to try. All the walls in my room have an inner and outer material, with the outer material set to 100% transparency by default. This allows the user to look 'through' the wall from the outside. Very handy when setting up cameras. But, of course, you have to switch the wall off before rendering, because the inside isn't transparent. The pic shows the transparent effect. mac
