Crypt Raider: Issues with Directional Light

[BokeTsukkomi]

Hello!

So, after chapter 7 (Lumen & Light Bleed) of the Unreal Engine 5 C++ course, I’ve clicked on “Build Lightning Only” to get rid of the preview labels in my level, but now the directional light is just illuminating all my level… I’ve added the floor objects on the ceiling and the edges to remove bleeding, and it was fine until I’ve clicked “Build Lightning Only”… What should I do to fix lightning in my scene?

Below you can see two screenshots: One from outside my dungeon showing the ceilings and edges (so it shouldn’t have any bleeding) and one from the inside showing how it looks with the directional light.

How can I fix this? Thanks

Are you using engine scalability settings?

[BokeTsukkomi]

Scalablity is set to Epic

What mesh are you using? Do you get better results if you block the light with box brushes?

[BokeTsukkomi]

I am using SM_Floor (both for floors and ceilings) and SM_Dungeon_Wall (for the walls) as directed by the videos.

I don’t know how to use box brushes.

I don’t know how to use box brushes.

It’s what was used to create the warehouse in a previous section
