    It seems SceneDepth and LowResolution render pass are broken. When material are using default rendering pass it rendered just fine.

    Hello,
    Thank you for reporting this.
    I tested and can confirm that I also have the issue.

    Now, I'm not sure if it is maybe expected or not, I will reach out to the developers to try to understand.
    In the meantime, you can circumvent the issue by multiplying the input UV coordinates of the scene depth node by two :

    If you're using the same shader on regular transparent & low resolution ones, you can setup an HLSL file and a custom function node to automatically switch the multiplier value.

    Here's the HLSL code :

    Code (CSharp):
    1. float _RenderQueueType;
    2.  
    3. void HalfResFix_float( out float o )
    4. {
    5.     o = (_RenderQueueType == 5)? 2:1;
    6. }
    7. void HalfResFix_half( out half o )
    8. {
    9.     o = (_RenderQueueType == 5)? 2:1;
    10. }
    And the setup of the custom function node:

    Thanks @Remy_Unity for the workaround :)

    Do you know if this one is gonna be backported to 2022.2/3 as well? it breaks Spaceship Demo's Glowspheres when in low quality mode

    As you can see in the bugtracker, it is "under consideration" for 2022.2.x :)
    Now, maybe it just went a bit under radar and took dust, but it is very likely to be backported, even until 2021.3.x
