It has something to do with Open GL. I'm still not clear what that is, but whatever it is means that you don't need nearly as many lights to light up a scene as you did in earlier versions of Poser. So that means that Poser 6 limits the number of lights it previews to 8. The lights that were made for Poser 6 and earlier versions often have more than 8 lights, and Poser 6 will only disply 8 of those lights and not the rest. However, even though the lights preview almost black in Poser 6, they still render the same as they did in Poser 5. Poser 6 also tends to pile on lights instead of replacing lights when you apply a new set. So go to "Windows" and "Python" and "Utilities" and "Delete all lights" before applying your lights. Unfortunately there is no "fix" for the way Poser 6 is displaying your earlier version light sets. However, making your own lights in Poser 6 is much easier than it was in earlier versions thanks to Image Based Lighting (IBL). Above is a tutorial to how to do that. Olivier was kind enough to write up a tutorial complete with templates. Also, below is another tutorial he wrote to explain lights in general: http://www.runtimedna.com/mod/forum/messages.php?ShowMessage=135278 Also, Face_off has a tutorial on IBL as well.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
