Working on the inside of the car. It's hard to take a screen shot with everything else showing so I'll just post a picture of the parts I'm working on.
If it's not shadow bleed from the lightmap then it's the screen space ambient occlusion. There are a bunch of different threads and methods about how to get rid of it, try searching.
Is anything else going to be on the screen besides what's pictured above? seems to be alot of negative space unless alot of writing is going to cover it up.
