Bunch of warnings for .meta inconsistency after package update in Unity 2019.2.12f1 HDRP, how do I fix that?

Since I upgraded HDRP, Shader Graph and Core RP Library from the Package Manager, everytime the assets database is refreshed Unity logs the following warnings:

  1. A meta data file (.meta) exists but its asset 'Packages/com.unity.visualeffectgraph/Editor/Models/Contexts/Implementations/HDRP' can't be found. When moving or deleting files outside of Unity, please ensure that the corresponding .meta file is moved or deleted along with it.
  2. Removing Packages/com.unity.visualeffectgraph/Editor/Models/Contexts/Implementations/HDRP because the asset does not exist
  3. Couldn't delete Packages/com.unity.visualeffectgraph/Editor/Models/Contexts/Implementations/HDRP because it's in an immutable folder.

I didn’t remove anything manually.
I checked if the folder can be found by using Windows Explorer but it’s not there, specifically:
there is a

folder but it only contains


What I’ve already tried (on isolated branch copies of the same project):

  • deleting com.unity.visualeffectgraph
  • manually deleting local package cache
  • removing HDRP and installing it again (that caused also vfxGraph to be removed and added again)
  • deleting .csproj files (useless, wasn’t it?)
  • search for any .meta file related to the vfxgraph to delete it but I couldn’t find anything

None of these solutions worked.

I’m sure there’s an easy solution for this I’m missing out, I hope someone out there can help me with this

I’ve also started getting these errors in Unity 2019.2.17f1 after upgrading to HDRP.

I’ve found a bandaid solution:

In Windows, navigate to your project folder, and find this location within it:


Then delete the ‘HDRP.meta’ file.

This stops the errors for this session. But Unity will create a new meta file when you start the program again, so you have to delete it every time.

You can actually avoid this problem totally, but this solution might have some issues in future versions.

Simply create empty folder named “HDRP” near this HDRP.meta file in path “\Library\PackageCache\com.unity.visualeffectgraph@6.9.2-preview\Editor\Models\Contexts\Implementations” and deny all rights for everyone for this folder.

Example of how this can be done in windows is here How to Create Undeletable Folders in Windows 10 - Make Tech Easier

After this unity will not delete this folder on launch and there will be no more warning messages.

Sorry for my English.

I suggest you go to Window > Package Manager in the tool, look for this extension and remove it. If you need it, try removing and reinstalling
