_CameraDepthTexture works in shadergraph, but not in custom shader

Hi, I am having trouble with a simple _CameraDepthTexture sampling. In shadergraph it works perfectly fine using this setup:



In custom shader I do:

Code (CSharp):

1.  
2. float4 scrPos : TEXCOORD01;
3. ...
4. uniform sampler2D _CameraDepthTexture;
5.  
6. //Then in vertex
7. o.vertex = UnityObjectToClipPos(v.vertex);
8. o.scrPos = ComputeScreenPos(o.vertex);
9.  
10. //Then in frag
11. float2 screenUV = i.scrPos.xy / i.scrPos.w;
12. float depth = tex2D(_CameraDepthTexture, screenUV).r;
13. return depth;
14.  

And the result is:


And this is what I get if I add depth = Linear01Depth(depth):



What am I doing wrong?

 

try multiplying buy the cameras frustrum
Linear01Depth(depth) * _ProjectionParams.z
I recall its default is clip space I could be wrong
