If I save the general lighting scheme as a lighting preset, then each time I apply the general lighting scheme it will ruin the configurations of the character specific lighting schemes that I have set up individually in each scene that I'm importing, and also that I've saved with the characters in the characters folder. I might be reaching some form of limitation, but I'm not sure. If anyone has downloaded the "War Room" set, the artist used at least a dozen lights, and my scene goes bunk after I import in any sort of character with parented lighting. I think Doozy may have a good point. Perhaps Poser thinks I'm importing the same lights that already exist, just in different locations. Anyway, I thought each light was only supposed to exist in one place at one time, but best judge for yourselves. In this case Poser deleted my original GUN RACK LIGHT and renamed the imported light to GUN RACK LIGHT, and Poser deleted SHOP KEEPER LIGHT but still registered it in the Light selector and also the second imported light got renamed to SHOP KEEPER LIGHT, so two names appear, but only one light exists.
