Trying to build light but shows me a weird message

Hello everyone, I keep trying to build light but ue5 doesnt let me. It shows me this message, could sommebody tell me what it means and how i can fix it?

The message says this:

No importance volume found and the scene is so large that the automatically synthesized volume will not yield good results. Please add a tightly bounding lightmass importance volume to optimize your scene’s quality and lighting build times.

It’s a volume you have to put around the scene, to tell it which parts of the level to concentrate on when building light.

It’s available in the actors placement panel.

Hello, i’ve tried what you said but it still doesnt work. Any other way?

If you put an importance volume in your level, you won’t get that error any more… :slight_smile:
