Can I use the PPS API by just installing the Universal RP

Unity Engine
1

I’m using the URP 7.1.5 w/ no other PostProcessing package dependency, it appears to now include the PP stack by default but I can’t find the UnityEngine.Rendering.PostProcessing namespace anymore.
Do I have to install the PPS 2.1.7 as well to be able to customize the stack by script?
Isn’t all of the PP Stack included in the URP? Or maybe there was a major change in the API that I’m not aware of?

Unity have once again made some major API changes as soon as something starts to look stable (post-processing v2). Now, the “Universal Render Pipeline” has successfully broken every custom post-processing effect, now requiring of them a non-trivial amount of time to re-setup, and maintain.

The message from Unity is quite clear in this API change: If you want to use URP, use URP as is. Don’t bother trying to add anything to it, because we’ve shown no indication that it won’t break again in the future. They can’t even keep the API for a float parameter stable between two minor versions (2019.2 & 2019.3).

To more directly answer your question, URP has its own postprocessing jammed in. PPv2 and other third party effects (seemingly, I hope I am wrong) just seem to not work at all in the latest 2019.3 build.

Thanks for the response, I just wanna know does that mean the independent Post Process package is deprecated, because the Documentation of the package doesn’t reflect the new changes.

On a separate note do you have any official links or posts that clarify the new changes?

Unfortunately I do not, Unity have not been making it easy for us post-processing developers to keep up with whatever they’re doing - there are patchnotes but nothing that I’ve seen reflects the changes, or even if PPv2 is intended to be deprecated.

@GoGoGadget OK, thanks for the reply.
I could find how to tweak the current effects but apparently writing cutom effects in URP isn’t available yet.
At least we have one less package to worry about.

So there’s no longer an API available in URP for post processing effects? That means the whole approach written about here:

https://docs.unity3d.com/Packages/com.unity.postprocessing@2.1/manual/Writing-Custom-Effects.html

Isn’t being carried over? Sigh.

It’s work in progress last I heard, could be ready by 2020.1 release date.

@mephistonight Concerning PPv2 they decided to support it in URP through 2019.4 LTS
