Uhoh. You have a large number of lights? Hmm.

A Python script could be built to automate that. However, the bigger question is, why do you have a large number of lights?!?

Which Poser are you using? In particular, are you using a large number of lights because you're in Poser 5 and do not have IBL?

Faking ambience with a large number lights is just not the way to go with Poser 6 and up. You should be using IBL.

Many Poser 5 light sets were created with a ton of lights and no shadows on most of them, because making 20 or 30 good-quality shadow maps would take a loooong time. Light sets like that will always produce those glowing surfaces.

If you're using Poser 6 or better, you really only need two lights for basic even lighting of a single figure. Sometimes you use one more as a rim light (from behind). You never need more than 4 to do a portrait.

After you come back and tell me which Poser you have, we can talk about what to do. If you have Poser 6 or better, I'll show you how to use IBL and one or two directional lights for good portrait lighting.
