Question HDRP Stencil Buffer

Hey! Im trying to create holes in walls using the stencil buffer but im not experienced with shaders. I found some shaders online to write and read from the stencil buffer in the hdrp

The write stencil code:

Code (CSharp):

1. Shader "Custom/StencilWriteShader"
2. {
3.     Properties
4.     {
5.         _StencilMask("Stencil Mask", Int) = 0
6.     }
7.  
8.     HLSLINCLUDE
9.  
10.     #pragma target 4.5
11.     #pragma only_renderers d3d11 ps4 xboxone vulkan metal switch
12.     #pragma multi_compile_instancing
13.  
14.     #include "Packages/com.unity.render-pipelines.core/ShaderLibrary/Common.hlsl"
15.     #include "Packages/com.unity.render-pipelines.high-definition/Runtime/ShaderLibrary/ShaderVariables.hlsl"
16.     #include "Packages/com.unity.render-pipelines.high-definition/Runtime/RenderPipeline/ShaderPass/FragInputs.hlsl"
17.     #include "Packages/com.unity.render-pipelines.high-definition/Runtime/RenderPipeline/ShaderPass/ShaderPass.cs.hlsl"
18.     #include "Packages/com.unity.render-pipelines.high-definition/Runtime/Material/Unlit/UnlitProperties.hlsl"
19.  
20.     ENDHLSL
21.  
22.     SubShader
23.     {
24.         Tags{ "RenderPipeline" = "HDRenderPipeline"
25.         "RenderType" = "HDUnlitShader"
26.         "Queue"="Geometry+1"
27.          }
28.  
29.         Pass
30.         {
31.             Name "Forward Unlit"
32.             Tags { "LightMode" = "ForwardOnly" }
33.  
34.             ZWrite Off
35.             ColorMask 0
36.  
37.             Stencil
38.             {
39.                 WriteMask [_StencilMask]
40.                 Ref [_StencilMask]
41.                 Comp Always
42.                 Pass Replace
43.             }
44.  
45.             HLSLPROGRAM
46.  
47.             #pragma multi_compile _ DEBUG_DISPLAY
48.  
49.             #ifdef DEBUG_DISPLAY
50.             #include "Packages/com.unity.render-pipelines.high-definition/Runtime/Debug/DebugDisplay.hlsl"
51.             #endif
52.  
53.             #define SHADERPASS SHADERPASS_FORWARD_UNLIT
54.  
55.             #include "Packages/com.unity.render-pipelines.high-definition/Runtime/Material/Material.hlsl"
56.             #include "Packages/com.unity.render-pipelines.high-definition/Runtime/Material/Unlit/Unlit.hlsl"
57.             #include "Packages/com.unity.render-pipelines.high-definition/Runtime/Material/Unlit/ShaderPass/UnlitSharePass.hlsl"
58.             #include "Packages/com.unity.render-pipelines.high-definition/Runtime/Material/Unlit/UnlitData.hlsl"
59.             #include "Packages/com.unity.render-pipelines.high-definition/Runtime/RenderPipeline/ShaderPass/ShaderPassForwardUnlit.hlsl"
60.  
61.             #pragma vertex Vert
62.             #pragma fragment Frag
63.  
64.             ENDHLSL
65.         }
66.     }
67. }

The read code is the same the only changes are the render queue, the stencil part and the Color Mask

Code (CSharp):

1. "Queue"="Geometry+2"
2.      ZWrite On
3.      ColorMask RGB
4.      Stencil
5.             {
6.                 Ref [_StencilMask]
7.                 Comp [_Compare]
8.             }

It works fine:


But I need the wall material to be a normal HDRP Lit with textures and etc... I copied an empty shader graph code and inserted the stencil part from the read code but it didnt work, its a massive 9k line code and I dont know where to edit it to make it work.

If anyone knows how to change the stencil buffer on the default Lit shader, I need some help

Thanks!
