I have tried so much but nothing I do works i'm not really new to scripting I've just never changed the lighting before... Need help please!!
Change the lighting settings: * change all colors to 0,0,0 (it's black) * change brightness to 0
Launch the game, and... Tadaam !
Using a script to change properties is fairly easy.
To change a property of lighting you'll first want to get the Lighting service, then set one of it's Properties. This works almost exactly how setting a Brick's color works. The only exception is Lighting has different property names and some properties are Color3 values.
So, to change a value of lighting, you'd do this:
game.Lighting.Ambient = Color3.new(255/255, 0/255, 0/255)
What that does is set Lighting's Ambient property to a Color3 value. Some Color3's have their values between 0 and 1, some use numbers between 0 and 255. Ambient does 0 to 1, which is why I'm dividing by 255.
If it't not local lighting, you could go to roblox studio. Then hover over to view->properties and in the WorkSpace->Lighting-> and edit the ambient
