This is a semi difficult one. Depending on if this is for while programming and setting up or live I would do this one of 2 ways.
Live I would use programmer and manually set house lights to desired intensity. This overrides cues and can be clear clear Ed.
Programming and possibly live since less chance of mess up have a quick cuelist or use programmer to set your houselights at full and park your houselights group. Then clear if programmer or release is cue. The way to turn this off is through unparking. An override will work in same respect but would have to be released. Parking is nice because the lights can not change at all without any fear of messing up.
