Question Shader depth behaving differently in Scene and Game window

Hi all,

I have written a custom shader that would produce the pink edges based on depth proj. But in the game view, instead of the pink edges, it does a weird projection of the whole scene view as in the second image. The mesh with the custom shader is a large plane. The pink is a color selected by me, it is not a missing texture.



The mesh with the custom shader is a large plane.


This image is taken in scene view and working as intended. The pink edges should only appear when it detects a mesh.


This image is taken in game view where the custom shader will project the exact image in my scene view.

Here's how the code looks

Code (CSharp):

1. uniform sampler2D _CameraDepthTexture;
2.  
3. v2f vert (appdata v)
4. {
5.      o.screenPos = ComputeScreenPos (o.vertex);
6. }
7.  
8. fixed4 frag (v2f i) : SV_Target
9. {
10.      half depth = LinearEyeDepth(SAMPLE_DEPTH_TEXTURE_PROJ(_CameraDepthTexture,UNITY_PROJ_COORD(i.screenPos)));
11.      half4 foamLine = 1 - saturate(_Foam * (depth.r - i.screenPos.w));              
12.      col += foamLine * _FoamTint;
13.  
14.      return col;
15. }

I've tried to change the render queue to a different number but the results are the same.

Can someone enlighten me why the game and scene views are producing different results? Thanks in advance!
