Try the Torch script The Aaron said: Torch can do that. This will toggle global illumination on and off for the page the token is on: !global-light <token_id> Dynamic lighting can be turned on with this: !nighttime <token_id> and off with this: !daytime <token_id> (You might be able to just select a token and run the command, I can't remember... =D) This is a pretty old script, so pardon the warts. =D
