1. Open the user's attached project
2. Open scene 'Scenes/SampleScene'
3. Make sure that 'Poison Area/Green Cloud Mist' has 'Texture Sheet Animation' enabled in its Particle System
4. Enter Play mode and wait
Expected result: The Particle System runs without issues
Actual result: After some time, the error mentioned in the notes will get thrown repeatedly
Reproducible with: 2019.4.32f1, 2020.3.22f1, 2021.1.28f1, 2021.2.3f1, 2022.1.0a15
Notes:
1. Error thrown: Assertion failed on expression: 'all(sheetIndexNormalized >= 0.0f) && all(sheetIndexNormalized <= 1.0f)'
