In Poser 5 and lower, you needed upwards of 20 lights or more  in most scenes to get adequate lighting.

With Poser 6 and IBL, that all changed!

In Poser 6 and up, you can have as many lights in the scene as you want, but only 8 of those lights will preview.  They will all render, but they won't show the approximate lighting in preview.  Please note that any lights in the scene that are turned off, count towards those 8 lights!

See this thread to learn how to make your own lights in Poser 6 and up

"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
