"textureSheetAnimation.startFrame" acts differently comparing to Start Frame on the Particle System Component



How to reproduce:
1. Open the user-attached project “textureSheetIssue”
2. Open the “SampleScene” scene
3. Select the “ParticleSystem” GameObject in the Hierarchy
4. Under the “Particle System” Component on the “Texture Sheet Animation” change Start Frame to 5, observe the results and change it back to 0
5. Under the “Texture Sheet Feedback (Script)” Component change Start Frame to 5
6. Compare the results

Expected result: Start Frame set by the Script looks the same as set by “Particle System” Component
Actual result: Start Frame set by the Script is behaving differently

Reproducible with: 2021.3.15f1, 2022.1.23f1, 2022.2.0f1, 2023.1.0a21
Couldn’t test with: 2020.3.41f1 (Script and Particle System errors)

Reproducible on: Windows 11 Pro

  1. Resolution Note:

    It's true, but changing it risks affecting existing content. I've logged a documentation bug for us to update the scripting api reference to explain thata the value supplied from script is supposed to be in the 0-1 range.

    It's done like this so that adding/removing frames does not necessarily invalidate the existing setting of this value.
