Error messages from logs (syntax-highlighting is supported via Markdown): Opaque Layer Mask does not work

I wanted to create a plane where the user can see through it like a window. It would be amazing if they could see Skybox through it. I wanted to create this functionality using forward renderer with layer mask. Skybox would be a massive sphere with cubemap material.

Expected behavior:

A sphere to be only visible through a quad.

Observed behavior:

A sphere is always visible.

How to recreate this behavior:
Follow this tutorial.

Impossible Geometry with Stencil Shaders in Unity URP

For my case, the object is sphere is in 7:Stencil Layer I created. The quad is using material with following shader.

Shader "Hatlab/StencilSkybox"
{
	Properties
	{
		[IntRange] _StencilID ("Stencil ID", Range(0, 255)) = 0
	}
	SubShader
	{
		Tags
		{
			"RenderType" = "Opqaue"
			"RenderPipeline" = "UniversalPipeline"
			"Queue" = "Geometry"
		}
		Pass
		{
			Blend Zero One
			ZWrite Off

			Stencil
			{
				Ref [_StencilID]
				Comp Always
				Pass Replace
				Fail Keep
			}
		}
	}
}

I've set the Stencil ID to be 1 in material.

In the URP-HighFidelity Renderer, find the Filtering.
Disable Stencil Layer for Opaque Layer Mask and Transparent Layer Mask.
I've enabled Stencil with Value to be 1, compare function to be "Equal".

Don't forget to change the render to be URP renderer at Assets/Settings for Camera. You can change it at Camera component at Camera.

Interestingly, it works correctly on Game window and App Sim Target.
However, when I build it and play it, it does not behave as it should be.

I don't know what is causing this issue. Is this even right way to approach this? I want to recreate identical behavior by making custom shader but I lack knowledge in Shader yet.

Hi @hatlabuvic
I followed the steps you laid out here, and I was able to get it to work. Try using the Balanced Renderer instead, I am trying to track down exactly why (see edit), but I think it is falling back from the HighFidelity-Renderer to the balanced one anyway. If that doesn't work let me know.

edit: It looks like by default there is a fallback set in the quality settings. I would recommend using the Balanced or Performant settings anyway.
