Lighting bug, lighting without lightsources

Where is the lighting coming from? As you can see there are not light sources or anything else that could make it appear lit.

I just deleted everything from the map except that one mesh to figure out where the light is coming from when I have all lights turned off. Looks like there is some strange bug in the editor.

Does the mesh look the same in Unlit mode?

No, there it looks unlit

To solve this, just change the material type of your object to unlit

If you want to do this to the entire scene, try messing around with the post processing volume settings

I now copied everything in a new blank map, there that mysterious lighting was gone.

I don’t want anything unlit, I want my scene lit with the lights I put in the scene. Instead it was lit with light(s) that don’t even exist which must be a bug.

great, I’m glad you solved it
