How do I disable lighting or change lighting layer paramater or like delete that layer from events?
No that just hides the objects on that layer, what i want to do is to disable the light or change the ambient light to white.
you could make a big white light that covers the entire screen and show that and hide the other lights
You can delete the light layer and move the light object to another layer, right? This is already in the IDE. Sorry, if I did not get your question
I think he wants to use the lighting layer for some times but not all of the time, and be able to disable it while not using it via events.
Ah, Ok got it. 
An extension or feature like that would be great.
