Particle System with View Render Alignment and drawn with DrawRenderer are facing towards Scene camera in Game View

Package: Scriptable Render Pipeline HD

-

How to reproduce:
1. Open attached project "FireRendering.zip" and scene "Scn_FirePass"
2. In Hierarchy window, expand "_CustomRender" and select "Particle System"
3. In Scene view, fly around the particle system and observe the Game View particle

Expected result: the Game View particle is facing the Game camera
Actual result: the Game View particle is facing the Scene camera

Reproducible with: 2019.3.0f6 (7.1.8), 2020.1.0a20, 2020.1.0a21 (7.1.7)
Could not test with: 2017.4.36f1, 2018.4.16f1, 2019.2.20f1 (HDRP and "custom pass volume is not recognized" errors thrown), 2019.3.0f5, 2020.1.0a19 due to another bug case 1195214

  1. Resolution Note:

    Hello,

    In the code of the custom pass, you're missing the override to AggregateCullingParameters, since the Shuriken particle system is only rendered in the custom pass, it never goes to the culling of the camera (which is when we compute the orientation of the particles). By adding your layerMask to the culling parameters, the particle system will be updated during the culling.
    Here is an example on how to do so: https://github.com/alelievr/HDRP-Custom-Passes/blob/11f347481266cb9576c65e0d9681d53dfcc95bec/Assets/CustomPasses/Liquid/Liquid.cs#L45
