I have checked that my models are generating UV maps. All lights are “baked”. And this is the “screenshot” of my lighting rendering setup. Sorry for the picture but I am still not able to take a quick screenshot from windows.
Thanks a lot for your kind help

I have checked and the console said that I could not combine meshes. So I found out that I was supposed to enable read and write on the models. Let’s see what will happen. Thanks
I had a problem: failed to copy lightmap snapshot assets to directory.
I decided to change to Enlighten and it works now, it builds. But I have tried to check also the Generate Colliders but still the build forgets about the lightmaps. Which are still visible well calculated both in the SCENE and in the GAME view and also when I PLAY it. I even changed the way some lights are Realtime and baked, but nothing happens on the build side.
Do you have any idea? I would like to present this work this Thursday and I will eventually use the unlit version. though I really hope to find a solution in the meantime. Thanks everyone
I have also tried on a Mac to create a standalone version for OSX. Same results, same projects: scene and play working. Build does not.
Thanks in advance
Hi, why are you using both realtime and baked gi? Please untick one of them, and set Auto generate to false (the toggle next to the Generate Button).
I have done a talk explaining most of these settings if you are intersted: Baking at the speed of light: Lightmapping for beginners - Unite Copenhagen
Hope that works 
hi, thanks, yes, I have removed real-time, removed auto generate lighting on all the three scenes. and I have watched your amazing explaining (also previous ones) before writing here. I am actually very happy that you answered me
I am attaching here two screenshots, one from the editor and one from the built version.
super thanks in advance!
Just for the record, I subscribed to Plus and I am also working with external programmers to give me a help.
Update: I have discovered that under Graphic and Quality there was not a render pipeline set. Hence I discovered I need one, Hence I discovered Render Pipeline exist!!
I discovered I need either Universal or HD. Will this be the solution?
Unfortunately no. I understood that even if there was not URP as renderer there was already a sort of built-in renderer. In fact even with URP the games builds perfectly without lightmaps. So, I am still where I was at the beginning…
SCENE VIEW: perfect
PLAY VIEW: perfect
BUILD: no lightmaps
so the result after all is this: I am paying 500 euros one person to solve it. case closed
Hi, sorry for a late reply. May I ask what the actual issue was?
And in the future, when we see that a thread has a lot of replies, we might skip it and look at threads with no replies. I think that could be the reason why we missed replying to this one, sorry!
Having the same problem. any insights are appreciated. Thanks.
Also got the same issue, how to fix? Some rooms do have the light others dont. I turn off rooms when game starts, but surely that couldnt be the reason?
I was having the same issue. Solved it by setting the Project settings>Graphics>Lightmap Modes from Automatic to Custom
This worked for me too, thanks!
Unfortunately this was not the solution for me 
This solution worked for me too. Thanks.
Please send the persons contact, we are having the same issue.
have you tried URP ? maybe it is because of material ?
