dots build loses renderer features

I added a URP renderer feature that lets me see the player through walls using the renderer features. It works fine but when I do a windows build it no longer works?
Any ideas? Using Entities .17 in a game object ecs hybrid project

So it works in the editor, but does not work in a build?

Would you be able to submit a bug report for this?

I was using deferred renderer with custom renderer features.
Decided to try forward - didn’t work
Tried fresh URP Pipeline High as well adding renderer features.
Tried it with Highlight Plus asset renderer feature only.
So nothing working.
Unless you have any other theories (I am using an unsupported ECS Build? )
Unity 2021.216.f1
Then I could submit a bug report?
Yes works fine in edit but not the build executable.

If it works in the editor but not in the player then one possible theory is that for some reason the required shader variants are not included in the build.

Also, I believe 2021 based versions are not supported with ECS yet.

What could I do about the shaders? Don’t know anything about it…also tried 2020 it’s with the same results.
