This was the bias issue, which should now be closed.

@reduz IMO nothing has changed so far (c2240a2)
in relation to this issue, please check the example project.

I just cant figure out whats going on and cant spend more time on this. For 3.1 will use a different algorithm for baking anyway.

[reduz]

Kicking this to 3.2, as a different baking algorithm will be used.

Fixed with the new lightmapper in 4.0-dev.

#40035 will also likely fix this in 3.2.x once it's merged 🙂
