GI Glitches on Lightmap. Dark Spots

Hey UnityForum,
i have a small problem with my lightmap.
my scene is lighten very great, but on some parts of my architecture there are darker spots than there should be. I dont know what causes these dark glitched spots. Maybe you had similar problems and could tell me what i was doing wrong.

Here is an example:

 

I'm not sure what I'm looking at.

Is everything okay with the lightmap UVs?

Everything okay with the normals?

 

I always let my UVs generate from unity itself. And i have no textures/ normal maps

 

I don't mean normal maps, I meant the normals of the models themselves. I'm still not sure what I'm looking at, but some models look like they might have flipped normals?

 

the weird thing is that they are all prefabs and as you can see even the same duplicated prefab is sometimes well lit and sometimes not well lit. PS: youa re looking at an archtectural megastructure made of prefab parts.

 

What does the texel validity view show?

 

i cant sellect it. its light grey :/

 

Are you using Enlighten? Can you post a better picture? I really don't understand what I'm looking at.

 

yes sure. give me some minutes. Thanks for helping btw yes i am using enlighten

 

here are some screenshots ! : https://imgur.com/gallery/HMjiR

 

Try the following: Raise lightmap resolution to 2 (leave indirect resolution to 1).

Select the file of those column things (which look consitently wrong I think) and under normals and tangents, switch normals to Calculate and see if that improves things.

 

The baking is going to need about 3 hours brb then ! thanks !

 

baking done, but not a rea change. still black spots, but some of them are ok now. but only a few
