How to Make It Dark Underground?

How do you make it dark down there like you show in your video? In my case, there is sunlight down there, and my players don’t think that’s fun. How do I enable it so that it’s dark down there?

Hello, I have the same problem. Is there any information available here yet?

That's a glitch with Rust's lighting system. The trick is that if you build a basement under the water (can be on a beach too), it will be dark in the basement.
