I know when I apply a texture and then change my mind, I can reapply another one and it over-writes it. But does the same thing apply to lighting presets? I can't for the life of me figure out how to do my own lighting in Poser 5, so I depend on ones that I've found free around the net. However, not all are nice so I have to try a few of them before I find one that is "sort of" ok. What I'm wondering is when I do this am I getting a build up of lighting, or is the most current one over-writing the previous lighting applications? If they don't over-write other lights, how do I delete the ones I've applied that I no longer want?

"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
