Static lighting produces blotchy shadows

In lack of better terminology, when I bake static lighting I get rather bad results. These “squares” appear and it seems like the Lightmass should be able to produce better quality seeing as the lightmap resolution is higher than that.

This is baked on production quality level.
I havent gone thorugh the Lightmass settings in detail yet, so maybe I have some settings in there that are not correct?!

Anyway, any help is appreciated :slight_smile:

Did you try to disable the “Compress Lightmaps” option?
On the other hand, your “Indirect Lighting Smoothness” is unusually low.

you have entered a comma symbol in the static lighting level scale field. Same error in other entries

Some countries use commas for the decimal point lol
