I have downloaded a few room type props but when I render them it does not matter how the lights are setup or how many are used the render turns dark to black..... I cycled through a few setups but the gremlin insists on turning the damn lights off. Someone will have a simple answer as usual and until then I'll restrain from trashing the computer. Thanks, Tommy.

Have you made sure that the lights are inside the room and not blocked by walls or the cieling? If you use infinite lights, they are by definition outside the room. You need to place spotlights in strategic positions within the rooms boundaries to make it work.

Hi - I had this problem with some rooms. In my case, I solved it by turning bits of the set invisible, like a wall or roof. With some room props you can't do this, and in those cases I had to light everywhere with spotlights rather than directional lights. I'm sort of a newbie myself, but perhaps this will give you something to try while waiting for a better answer. John

Thanks guys, I think you are making sense, right now I'm reading the PDF manual. (on lights) Tommy.

Also remember that the rather basic rendering engine in Poser does not work with ray tracing, radiosity and other advanced features. This means that light will not bounce around in the room. It will only shine where you point it. Given these restrictions in the Poser rendering engine, the placement of individual lights becomes more critical. When using spotlights, make sure to play with the "Angle Start" and "Angle End" dials. These controls the "spread", the size of the light cone. As default, it's set as a quite narrow cone, so it usually needs to be adjusted when creating a spot light.

You can also select individual lights and dial their shadow values down - if set to 50%, about half the light intensity will penetrate anything - I use that setting or lower for moody interiors, castles, dungeons, etc. You can also select an object such as a roof or a wall's properties and turn off it's shadows entirely so all lights go thru that item unimpeded.

It's also worth double checking where your camera is - I've been known to place the dolly camera outside of a wall and, hey presto! - No render. Doh! :-) Dave :-)
