I can not understand what was happening, but after baking appear strange dark artifacts (big spots) at some objects. I found similar artifacts (blaсk dots) in other topics, but I think they have another reason.

Lightmap UV generation and Preserving UV’s is enabled.

Do they go away if switch to just “Directional” (not directional specular) and rebake?
