I have been bashing my head over this for a hot minute now and can't figure out what is the cause of the issue. In substance painter my mesh and lighting look fine. There are no artifacts or anything. Nor are there any shading issues.
However when I bring everything over to Unreal certain parts of my mesh are darker than everything else.
I can't figure out why that may be.
This is in engine
