GUID conflicts - 2018.3

I am getting hundreds of the following errors:

GUID [d4351734f8a0aaa42a51a99db92e92e2] for asset 'Packages/com.unity.postprocessing/PostProcessing/Editor/Tools/ResourceAssetFactory.cs' conflicts with:
'Assets/Gaia Dependencies/PostProcessing-2/PostProcessing/Editor/Tools/ResourceAssetFactory.cs' (current owner)
We can't assign a new GUID because the asset is in an immutable folder. The asset will be ignored.

This is happening for multiple objects.

I found this ref https://issuetracker.unity3d.com/is...plicate-guids-for-plugins-shipped-in-packages so I updated to 2018.3, since the article states that this issue has been resolved. Yet, I am still having it.

I asked about this on reddit and was told I could simply change the guid in the .meta file. However before I do that I thought I would check here to see if I can get confirmation of the issue or another solution.

Thanks kindly

 

Hitting the exact same issue here, also with 2018.3.0f2 and Post Processing 2.1.2 via Package Manager.

 

Same problem here

 

I know this is not helpful, I had to restart my project because of this and a few other issues, mostly because of the other issues. (I have several beta assets)

You may consider creating a testbed project and importing your assets to see when/if this happens again. Sorry I haven't found an actual solution

 

I used the recommended solution from the reddit thread you found, that is, open all of the .meta files which are listed as warnings in Unity. Then, use a website such as guidgenerator.com to generate new GUIDs (don't forget to turn off "hyphens") and paste a new GUID into each of the .meta files to replace the existing GUID. I had to do this to ~72 files, so it took about 10 minutes to replace them all. I even left Unity open, when giving Unity focus again, it detected the changes and reloaded the Assets. Now everything works and I have no more GUID warnings!

 

Awesome! Good to know.

I had other issues, so starting the project over and moving components was of value for me. You rule for trying that out.

 

I used this tool to generate GUID, https://codebeautify.org/guid-generator

 

Thank you kindly, I will keep this in mind if it happens again.

 

What the error says exactly is you have 2 postprocessing folder, one in com.unity.... and one in your project. Delete the one from your project, no more conflict ;p

 

Thanks Devil, I ended up having to redo the project because of a number of issue, but it's great to know the answer. You rule. Have a great week

 

Oh man this was so helpful... I know this is a year old post, but this simple comment helped me fix the problem that bugged me to hard. I read so many posts about how people had to completly redo their own work and make a new project and so on and I myself gave up and wanted to just ignore those messages, cuz everything else worked fine.

For those who still don't know- Open your project file (The one you create when you make a new project) and then follow the path that Unity says is problematic. For me it was -project name-/Assets/Plugins and -project name-/Assets/Editor.
I just deleted those files and all works

 

i re-created this issue by simply ctrl+D (duplicate)ing a texture. seems as if it keeps the same GUID through the dupe

 

Thank you very mush 'DevilCult' That solved the problem
it was a conflict between two Post Processing Folders

 

The solution for me was to use this tool to generate a GUID (it is important to disable the usage of hyphens): https://codebeautify.org/guid-generator
Then replace the GUID in the .meta file of the problematic class with the newly generated one.
