An asset is marked with HideFlags.DontSave but is included in the build

I can't build my project as I'm just getting errors in the log. This was working fine earlier, and the problem seems to be caused by the fact that I deleted a Scene (that was just for testing).

I've seen a couple of threads suggesting deleting Library, deleting Project Settings. Neither of those has solved the issue.

Any ideas?

 

Make sure you're not trying to include any editor-only scripts in your build.

Also, what is the Asset Name? It's hidden below the fold in the console and might provide some more context. https://forum.unity.com/threads/build-errors-after-upgrading-to-unity-2017-1-0f3.482928/

 

If you're using Alembic in your project, we found scenes (and presumbly prefabs) where a nested mesh renderer underneath a gameobject with an Alembic Stream Player would stop the build from completing. Such behavior is intended. Alembic is marking all children as 'HideAndDontSave' because otherwise every time you change your alembic frame, you will get a scene bloat.
The solution this problem is to parent the ABC and FBX to a common GameObject and make a Prefab out of that instead of adding the FBX Prefab to the ABC Prefab.

 

Copying scene files to a new scene solved it.

 

Just want to add in case it helps anyone else, I had a script that was mistakenly setting the hide flags on a shader that I was dynamically loading to DontSave. Unity somehow reserializes that and it was causing issues, despite nothing in the meta file or anywhere else indicating that it had changed.

 

In my case, I had a scriptable object that is for editor and I placed it incorrectly inside the resources folder, once I moved it out from resources folder, everything build fine

 

Very helpful - I have the same issue with an alembic-file. But your solution didn't work yet for me.. Have to bruteforce it a bit

 

And btw. Make sure there is NOT A SINGLE old prefab file anywhere that coudl cause the bug again. If you dont find all prefab files, simply copy the "bugged" fbx file and delete it then. Move the copy back and remake all the prefab files. They kills all thx fbx's links to other prefab files and solves the problem.

 

Leaving this for my future self, As said by Omar, I had a folder named resources (note that this is not THE Resources folder, some sub folder I created), after renaming it, everything worked fine.
