I am wondering if it would be possible to implement a progressive light swiitch. The idea is to switch on a rectlight that will simulate the sky / sun light flowing in a dark room (baked lighting as I am working on a VR project, the rectlight would be movable).
So far, since I have already composed my double doors BP (open when triggering a switch in a given zone). Switch on or off the light is not a problem either but I am wondering how to deal with the flowing light. Intensity should rise as long as the doors opens, gving the feeling that light is flowing in the room… Any idea ?
