A newbie here, I've been having a few problems.
I have copied events from the demo and even copied the script from the demo onto my own project and the lighting won't show up, the only time it has kinda worked is when I add the script line of,
$game_map.csca_light_need_refresh = true
This way also backfires in that it only active when being pressed or when on parallel process trigger, when being pressed, the light triggers and just as it went on it turns off. when on parallel process it just flashing's on and off like a rave. The map the event is in has a screen tint event as well but I have already told it to end the event after activation. The only other event's in the map is 6 transfer events out of the room.
