HDRP Custom Pass Renderer Selection only works with GameObjects using HDRP/Lit Shaders in Builds
Reproduction steps:
1. Open the attached “BackgroundSeparationTest.zip“ project
2. Open “OutdoorsScene” scene
3. Enter Play mode and observe the Game window
4. Exit Play mode and Build and Run the project
5. Observe the Build window
Expected result: GameObjects are colored regardless of the Shader used
Actual result: Only GameObjects that use the HDRP/Lit Shader are colored
Reproducible with: 2020.3.44f1
Not reproducible with: 2021.3.16f1, 2022.2.2f1, 2023.1.0a25
Reproduced on: macOS Monterey 12.6 (Intel)
Note:
- Cannot test on WebGL due to errors: “BuildFailedException: Platform WebGL with graphics API OpenGLES3 is not supported with HDRP”
- Couldn’t find the fixing version due to obsolete code being used that prevents reproduction

Resolution Note:
Hello,
The objects disappear in the build because you're using the "Deferred" rendering path in your HDRP asset. Selecting this rendering path will cause all the "Forward" shader variants to be stripped during the build. These variants are necessary for your custom pass, for more information you can see this section of the documentation: https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@15.0/manual/Custom-Pass-Troubleshooting.html#opaque-objects-disappear-during-build
To fix the issue you can either use "Both" in the rendering path settings or use another replacement shader to render your mask. The replacement shader can be created from the "HDRP Custom Renderers Pass" menu in Create > Shaders.
