Hello,
The postprocessing shader is included in the build even if no postprocessing is done in the scene.
Can be tested with the sample URP scene, by removing the post processing volume.
Using unity 2019.3.01f
Thanks!
Yes, I have also realized this. Maybe you could make an issue for it as well so that it can be tracked?
Ok. Submitted.
What is the issue number. Can you link to it?

Iāve also reported this previously Stripping unused Universal render pipeline shaders and textures on iOS build havenāt had any feedback on my bug reports though.
And itās not only the UberPost shader, there are also a bunch of built in textures related to post processing effects (like film grain etc) that are included in the build even though thereās no post processing.
I have the same issue. There are also a lot of FilmGrain texture that take up space in the build.
All that in a fresh 2019.3 project without any scenes or other files.

Still looking for the issue number
The bug I reported on this in October 2019 was closed in fogbugz when I checked now, but I canāt seen any explanation why. I canāt find it in the issue tracker either (though that might be because itās so hard to find things there). Perhaps they couldnāt reproduce the problem and never made an issue of the bug report. Iāve contacted them again asking them to reopen the bug and investigate it as itās clearly still a problem.

Also, I see that in my Android build, post process add the dirt lens textures ( even if I removed them from post processing settings ). This texture is 22mb size. 1/3 of my game size.
I am also seeing this issue. Unity 2018.4.19f
Edit:
As a workaround I used the Package Manager to uninstall PPv2, and did my build. It works but complicates doing a build.
I tought that was normal, and the Uber shader is kinda huge. lols
Back on this. They closed the ticket and said that itās normal for the shader to be included in the package and there is nothing they can do.
Could you guys please also submit a ticket ?
Any update on this?

Iām definitely not using a lot of those postprocessing effects listed, I can understand that some are probably needed for dependencies, but this is a bit silly to add several MB to a project just for using URP.

Hello, user @grapefrukt made a nice script that strips all of these before build, you can check it out here
We will add the option to strip disable (and then strip) post-processing from build.

Thatās great news @phil_lira . For future reference, when this is added could you add a reply here explaining where this setting can be found so we can all use it?

Heads up.
Iāve made a PR to address this issue, currently in review, which should get backported to the 8 and 7 branches.

What are the odds of this making it into 2019.4 LTS?
This is something we really want to add to the LTS release so this will hopefully arrive in 7.5 along with other fixes. I canāt fully say when weāll release that package but once we do I will try my best to include it.

Is this in 2019.4 LTS?
How I can strip all post-processing shaders and related assets from Unity builds using URP?
