Cancelling this 2023.2 tech release issue since the support for this release has come to end of life. Cancelling this 2023.2 port case does not affect any LTS or Unity 6 Beta/Preview that remain open.
Reproduction steps:
1. Open the “PS_test.zip” project
2. Open the “SampleScene” and Enter Play mode
3. Observe the Scene view (expected result)
4. Leave Play mode and select the two Particle Systems in the Scene
5. In the Inspector window, set the Particle Count (Emission > Rate over Time) to 200
6. Enter Play mode again
7. Observe the Scene view
Expected result: “S” (simulated) Particles are closely simulating their “P” (played) Particle counterparts
Actual result: “S” Particles are not aligning with the “P” Particles
