Post process Stack Stencil

Hello,
I created a custom PostProcess effect using the post process stack but I need to apply it only to some objects.

I think that I can achieve it using a stencil but so far my shader just ignores the stencil...

Post Process Effect Code:

Code (CSharp):

1.     SubShader
2.     {
3.        
4.         Cull Off
5.             ZWrite Off
6.             ZTest Always
7.            
8.             Pass
9.         {
10.             Stencil{
11.                     Ref    2
12.                     Comp always
13.                     Pass replace
14.         }
15.             HLSLPROGRAM
16.  
17.                 #pragma vertex VertDefault
18.                 #pragma fragment Frag
19.  
20.             ENDHLSL
21.         }
22.     }

 

Maybe you can try unchecking 'Allow HDR' , 'Allow MSAA' and 'Allow Dynamic Resolution' on your camera component.

 

If anyone stumbles upon this

I solved It by Rendering the things I wanted to affect in the Queue Geometry and the unaffected things on Geometry+1.
Unity actually has 2 Depth Textures:

*_CameraDepthAttachment
*_CameraDepthTexture

The _CameraDepthTexture is created before Geometry+1.
so for my PostProcessing Effects, I just used the _CameraDepthTexture to make this calculation.
