How do I turn off all light (for complete darkness)?

I am using unity for the first time and as a sound designer am not familiar with game engines (anything outside of audio really!).

I’m creating a game which uses audio as a navigation tool, and varies the amount of vision (using spot lights as the main source of light).

How would i turn off the main light completely, and implement spotlights which can be triggered on and off?

thanks

You can go to Edit>Render Settings and set the Ambient Light color to Black. This might work for what you’re making.

The Spotlights can be triggerd by code. Unity - Scripting API: GameObject.SetActive
Unity - Scripting API: Light
