    Iam making a HDRP decal shader, trying to project some numbers on a terrain. I'd like to replace UV coordinates with XZ coords from world position. But when I do that, the depth is basically set to the far plane of the decal projector, instead of the image being projected on the geometry. Is there any way around that?
    Here is what it should look like (using default non world space UVs):



    And what Iam getting:

    This was a bug, it's been fixed in the repository and should be available in the next preview release of 9.0.0 if you're using 2020.1

    We're experiencing the same issue in HDRP 7.3.1 Unity 2019.3
    Will the fix be backported? We aren't in a position to upgrade our Unity Version from 19.3.x, nor from 7.x for HDRP.
