Though I thought I ought to mention that there will likely be a new version soon, with a "debug" mode which I have added to clear up any stray lights that are left over if they fail to get cleared up as they would normally (in very low FPS scenarios for example). Once Arkgnt has fully tested it, that is.
EDIT 2: We should probably think about making a version adding lights to more FCOM creatures that would look good with lights. This is a bit of a difficulty for me to make as I don't have FCOM, or any overhauls actually (mainly because I don't actually *play* oblivion any more, I just mod :facepalm: ). With the scripting out of the way, you could probably go about doing it with relative ease, Arkgnt?
