In the script .gsc of my map, I have edit for set the lighting state 2 at the power on and in the .map I have put a light working only at lighting state 2
But when I start the map, the light is already working and when i switch the power on the light disable

Someone cane help me pls ? :c

By state 2 I assume you mean 1

0 = 1
1 = 2
2 = 3
3 = 4

The game sets the lighting state to state 1 at the start of a match

If state 1 isn't set up it still tries but remains on state 0

Make your power on state 0 2 or 3
