Hi, I have a problem with static lighting build, as the title says all of my meshes turn black after building. This is a screenshot of my editor when my lights are set to Stationary: [stationary] And this is what I got after lighting build: [baked] I’ve done some digging of my own on this pr…

Lumen doesn’t work with static lighting, and cancels all lightmaps. Just turn Lumen off ( project settings ), and bake again?

And I’m assuming the lightmaps are good?

I’m actually not 100% sure, but here is a random mesh in the scene: [lightmap] The shown UV is channel 1. When I import another mesh from another working project and bake it still becomes black.

You need to look at the UVs on channel 1 [image]

It is channel 1 (you can see the left arrow I’m pointing in my last reply)

Beg your pardon, now I see the arrow. Sorry, I have no other ideas. A lot of people seem to be getting this problem. I’d try just changing a lot of things to see what breaks. Does it work in a new map, does it work in a new project? Etc…

I got everything back to normal, by deleting all the lights and start over. I did not do this earlier because I reverted their values to default, but nothing changed. So I assume this is a bug. I was going to send a bug report but I have no idea what I did to cause it. But anyway, thank you so much…
