Question Migrating a project from 2019.2.3f1

I'm trying to migrate my project from 2019.2.3f1... everything works fine, except for the post processing effects.

I'm getting the following error, and I think that's the source of the problem:

GUID [9802e36ef1c38064d9bcd7bf2e01cccb] for asset 'Packages/com.unity.render-pipelines.lightweight/ShaderLibrary/Deprecated.hlsl.meta' conflicts with:
'Packages/com.unity.render-pipelines.universal/ShaderLibrary/Deprecated.hlsl.meta'
We can't assign a new GUID because the asset is in an immutable folder. The asset will be ignored.

In this blog post, there's the following text: [..and the Universal Render Pipeline (known as “Lightweight Render Pipeline” before 2019.3)] which apparently means the Universal RP deprecates the Lightweight RP... since both appear on the Package Manager, I thought I could safely remove the Lightweight RP but that doesn't seem to be the case. The error above mentioned indeed disappears after removing the LWRP and the post-processing effect works again, however all my prefabs became pink after that, besides all the my shaders are ShaderGraph shaders, and if I try to edit any of them, the editor shows a warning saying the master node is not supported on that render pipe line.

 

This worked for me when I had issues:

1. Re-enable LWRP from the package manager.
2. Update everything to 7.0.1+ (if it's been bumped since I last checked). (LWRP, ShaderGraph, SRP Core if you manually reference it).
   
3. Manually Install URP from the package manager (LWRP 7.0.1 is just a shell that redirects and upgrades things to URP)
4. You can then remove safely remove LWRP.
5. If there's still some weirdness, close unity, delete the Library folder, reopen unity.

 

Thank you.

Your post made me realize I just need to install the Universal RP... I assumed that when you removed the LWRP, the package manager only removed the LWRP package, but it also removes the Universal RP... why? I don't know, but that's not what you would expect.

Additionally I had to open and then save all my shaders.

Now I don't get any errors.... but the Post-Processing effect are still not working.... Any Ideas?

.

 

There's a new Post-processing stack for URP apparently, the old PP v2 stuff is no longer compatible.

I think more docs are forthcoming (the URP docs are just copies of the LWRP ones at this point, and still reference PPv2), but it sounds like it's now capable of some of the features that were introduced with HDRP, specifically it's tied to volumes now. Right now the volume documentation is in HDRP docs.

Custom PP will come down the pipe, but on the forums and discord the devs suggest seeing if the new custom renderers feature can do what you want.

Custom renderer examples: https://github.com/Unity-Technologies/LWRP-CustomRendererExamples

I'm assuming their goal is to have the primary issues and documentation worked out by Unite, and that's why the shift to URP is more dramatic and lacking in docs.

 

The Universal RP uses its own Post-Processing integrated into the Volume System like HDRP.
So just add a volume and create a volume profile and add your effects back.
GameObject -> Volume -> Golbal Volume or Right click in Heirarachy - Volume -> Golbal Volume

Select New and then add your effects


Currently, the Post Effects only show in the Game View so Scene View won't display any effects.

Also, there is an upgrade guide to getting your project working with the Universal RP. Not really any big changes except for post-processing though. The upgrade should be pretty seamless though.

 

I dug up the migration guide posted a few days back: https://docs.google.com/document/d/1Xd5bZa8pYZRHri-EnNkyhwrWEzSa15vtnpcg--xUCIs/view

 

Thanks for mentioning opening + saving all your shaders, this was the trick to get mine working as well!

 

Yes, if you have shadergraph shaders, they render everything pink unless you open + save them.

 

Thank you, but I'm afraid this doesn't work for me... I added the global volume as you recommend, but still I can't see any post-process effects yet.

Thank you I read it through, but I couldn't find there something helpful, everything mentioned there I've already done.

 

So maybe is not a good idea to migrate until all Unite events are over.

 

Ah yes, the last step is to enable Post-Processing on the Camera. Forgot to mention this one. After enabling you will also see Anti-aliasing shows up as well

 

Thank you again, but enabling Render Post-Processing triggers the following error:

Yep mine were ShaderGraph shaders too. They didn't reserialize automatically, but opening and saving them triggered a bunch of serialization changes to show up in source control, and then for them to start working correctly instead of rendering as pink.
