Baked light bleeding through model

Unity Engine

Hi!

I might be in the wrong place asking for help, so I apologize in advance. I have this basic 3D scene set up where I have both tried to have my walls as planes as well as 3D walls exported from Blender. Then I have selected all of my walls in the scene and set them as static, and then I have a pink point light set to baked lighting. After I bake my lightmap there are these bleed through pink lines appearing at the seems of connected gameobjects. Why is this and how can I go about fixing it?

Thanks!

Try increasing the margin between UV islands, either in Blender or in Unity, if you generate UV maps there.

Will try that out, but for a plane, would that make any sense? My plane being UV unwrapped even if it has loop cuts going through it horizontally would just be a flat 2D projection. Then there arent any UV islands to set margins between? Or am i thinking about it incorrectly?

Thanks!

Are there overlapping UVs? Or maybe you need to increase the margin to the edges, if you only have one, continuous uv island.

Yes! Giving more margin from the corners to the UV seems to have done the trick! Thanks a lot!
