Particle System bounds computed incorrectly when shape set to SkinnedMeshRenderer and model is moved in LateUpdate



How to reproduce:
1. Open the user's attached "PSBoundsShapeRepro.7z" project
2. Open the "SampleScene" Scene
3. Enter Play Mode
4. Press the "Pause" button
5. Select the "po_BurningStatusFX" GameObject in the Hierarchy window
6. Enable the "Show Bounds" property in the Scene view's Particle Effect window

Actual result: Particle System's effect bounds shape is behind the "unitychan" GameObject
Expected result: Particle System's effect bounds shape is the same position as the "unitychan" GameObject

Reproducible with: 2020.2.3f1, 2021.1.0b4, 2021.2.0a3
Could not test with: 2019.4.19f1, 2018.4.30f1 (Due to Particle System not working when downgrading)

  1. Resolution Note:

    Unfortunately this happens due to how the Particle System and Transform system are designed, and to be totally honest - we're not sure how we can fix it.

    We are going to close the issue for now, as we are not planning on working on it in the near future, given that we don't know how we could proceed to fix it.

    As a workaround , it is possible to set your own bounding box since Unity 2022, by setting renderer.bounds in script.

    Apologies for the inconvenience.
