VFX Particles receive shadow artifacts when using ShaderGraph with enabled shadows and Face Camera Plane Orient mode

-

Steps to reproduce:

  1. Open the attached project
  2. Open the SampleScene
  3. Observe the VFX particle in the Game view

Actual results: VFX particle is receiving shadowing from itself

Expected results: VFX Quad particle does not receive a shadow from itself

Reproducible with versions: 2022.3.61f1, 6000.0.48f1, 6000.1.2f1, 6000.2.0a10

Tested on (OS): macOS 15.4.1, Ubuntu 24.04

Notes:

  • ShaderGraph assigned to the particle's Output has Receive Shadow and Cast Shadows options enabled
  • The issue does not occur when Face Camera Position or Fixed Axis (Up) Particle Orient modes are used
  1. Resolution Note:

    We're aware of the issue, but fixing the issue requires adding a new feature (shadow bias). Hence we are closing this bug to treat it instead as a feature request.

  2. Resolution Note:

    Forward-ports for this version need to be handled at a later time.
