Lighting a hole in a landscape?

Hello,

I created a cave in my landscape, but the problem is that the cave is entirely black, even after I build the lighting.
I don’t understand what can I add so it’s not that dark…

What should I do?

Thank you

Built lighting doesn’t have global illumination yet but it’s coming (possibly in the next version according to the latest live stream). Once that’s added to the engine light will bounce into your cave. Until that happens you’ll need to fake it with manually placed lights.
