Hey, love your videos. Im dying just to chat with you and talk about my problems with current project. i have an important meeting this Monday and i need to fix my issue before that.

As you can see below, these black lines were never there. It just suddenly appeared after i added couple of meshes (kitchen items and some materials) but nothing changed to wall settings or project settings.

I tried changing map and fresh start in another project but got same result, bake was done in production mode at first but this image is in preview build

@Marty-TDK That looks like a 4.18 issue. did you update to 4.18 and is that when the issue occurred? If so 4.19 preview 5 should lessen that issue. Can you send some shots of your lightmap density and a shot of your light map channel uv’s.

I dont think you need to bounce your skylight 100 times, I would try 10 and see if it makes a difference. It should lower your bake times drastically.
