Been having this issue for 2 days now.
looks like im getting some weird bruising on my bedframe in my lightmap after baking.
If i remove the bed and sheets it seems to be better.
I cant for the life of me figure out why this is happening.
I have proper lightmaps aswell as having the correct lightmap assigned in the coordinate index.
I have been wanting to move on and do more to the scene but it has been such an EYESORE!
I uploaded photos below.
