1. Open the attached project from "SoftParticlesClipPlaneError.zip"
2. Enter Play Mode
3. Observe the smoke particles that are occluded by the floor plane
Expected result: Smoke particles are rendered up front
Actual result: Smoke particles are occluded by the floor geometry
Reproducible with: 7.3.1 - 12.0.0 (2018.4.36f1, 2019.4.29f1, 2020.3.15f2, 2021.1.16f1, 2021.2.0b6, 2022.1.0a4)

Resolution Note:
