    When I was doing the ParallaxOcclusion code for my URP+ pipeline following the HDRP example, I noticed a bug (or I'm wrong).
    In HDRP code we multiply viewTS by GetDisplacementObjectScale():
    Code (CSharp):
    1. float3 viewDirTS = isPlanar ? float3(uvXZ, V.y) : TransformWorldToTangent(V, input.tangentToWorld) * GetDisplacementObjectScale(false).xzy;
    But if we do not do this, then DepthOffset will work more correctly. Here are the screenshots:

    A very strange bug. The DepthOffset in general works very oddly with Pixel Displacement. It's not GetDisplacementObjectScale fault.
