I asked that same question not long ago runner ... from what I understand, there's no way to do it other than manually ... pain in the arse, isn't it? :-) One thing I'm kinda' in the habit of doing though, is when I try a light set and I don't like it, I "restore lights" to take it back to the default or previous state ... that way I don't end up with 50 lights with only two working and when I go to render it doesn't have to move through all of 'em. But, if anyone has any new suggestions, I'd sure love to hear 'em. Rhi
