Error: Failed to load [...] because it was serialized with a newer version of Unity

Downloaded from Git as a zip file, Unity launcher informs me that the project version is 2018.3.0b4 (but I also tried 0b6).

Both in 0b4 *and* in 0b6 I get spammed with these errors on opening:

Failed to load 'C:/Users/KillaMaaki/Downloads/FPSSample-master/Assets/ScriptableRenderPipeline/HDRP_Assets/HDRenderPipelineAsset.asset' because it was serialized with a newer version of Unity. (Has a higher SerializedFile version)

UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

Any ideas?

 

This did not happen for me with 0b6. I did get errors, but not that one. The errors I saw are in this thread.

 

You must download not as Zip, you must clone repo (18Gb) because it use LFS

 

Yeah I just figured that out after taking a peek at several .asset files in Notepad and realized they were actually just linking to files stored in LFS.
Whoops.

 

I wish I knew of the proper place to rant about this. My biggest beef is how Unity updates itself with new versions. It would be nice if Unity failed gracefully (in this issue and others I've seen), but really should be happening is a sense of backwards compatibility where I don't need to have 2 different installs of, for instance, Unity 2018.3.0f1 and 2018.3.1f1. I shouldn't need 2 installs - the newest version of Unity, especially in beta's, should be backwards compatible..how much more different cant it really be? Do the api's and classnames change that much? </rant>

 

Yah... It seems its best to nab your Unity Installer and keep it safe somewhere, then grab your FPS SAMPLE template version, and keep that safe too... Consider both now 'your version' of your game. So if a new unity/fps sample comes out, then you have to decide if you want the new fixes and toys, or to save the conversion time.

If you happen to need to download Unity 2018.3.0 B12 like FPS Sample 2.0 requires, you can no longer select it from the unity-hub v1.3.2 due to 2019's release...

But this link will allow you to download Unity 2018.3.0 B12 :
https://unity3d.com/unity/beta/2018.3.0b12

 

I now got this error after updating to 2018.3.6f1, but I don't use github. Any ideas?

EDIT: And I also download packages through the package manager not with github. The things that have this error are all materials that used the HDRP, so I've tried removing it and installing again, but it didn't work.

 

I am having same issue as Double-V, but started when unity crashed and when after restarting on all my scenes (even ones that were not open). However when I open a scene file in text editor it says � v� � 2018.3.5f1 ����$

I tried upgrading to 2018.3.6f1, but did not help.

Any ideas on how I fix this?

 

Well FPS Sample 2.0 required specifically Unity 2018.3.0 B12 https://unity3d.com/unity/beta/2018.3.0b12

Yesterday (2/28/2019) FPS 3.0 was released on git-hub:
https://github.com/Unity-Technologies/FPSSample
But, they have not updated any of the documentation on the website to reflect it.

The new 3.0 FPS sample requires Unity 2018.3.0f2
(this is the release 2018 Unity ! so that should make it more stable, right?)

Maybe update to FPS 3.0, unity 2018 prod, and see if it resolves and import your previous work. That's my plan, anyway...

Wish it was 2019! but I can make due with broken terrains I suppose.

 

I mean this happens in my own project, not in the fps sample.

 

my doubt is also - does it cause any problem while building the project??

 

I solved this issie by changing the platform to Android and then returning to Windows

 

I just love unity so much guys

 

In case anyone else has an issue with this error after cloning an LFS repo: for me it was fixed when I PULLED the LFS files. 'Fetch' was not good enough.

 

i don't think i'm supposed to do this, but anyone, can you guys help me at my thread for console logging? thanks

 

Bumping this as its true for Megacity
