    Got this error in a custom shader after upgrading from HDRP 10.0.0 preview.27 to HDRP 10.1.0 (Unity 2020.2.0b8).

    Appreciate any help resolving this error.

    @francescoc_unity I am getting another shader error after upgrading;

    Shader error in: unrecognized identifier 'HDShadowContext' at line 60 (on d3d11)

    Do you have any pointers on how to address this also, much appreciated!

    Without knowing your shader is hard to tell, but be sure "Packages/com.unity.render-pipelines.high-definition/Runtime/Lighting/Shadow/HDShadowContext.hlsl" is included somewhere before the shadow context is referenced.

    AFAIK nothing changed between 10.0.0 preview.27 and 10.1.0 regarding that, but I might have missed something.

    After upgrading to latest HDRP 10.2.0 on git (release branch), I get the following shader error:

    undeclared identifier 'ComputeScreenPos' at line 4663 (on d3d11)

    Is this something you would be willing to help me sort out (I know I am using git, but trying to keep up :))

    Same. Shaders that uses the built-in ComputeScreenPos function are no complaining about it being an undeclared identifier in HDRP 10.2.2 in Unity 2020.2.1f1.

    Add: #include "Packages/com.unity.render-pipelines.high-definition/Runtime/ShaderLibrary/ShaderGraphHeader.hlsl"
