UUM-77243
Regression
No
Minimum Vertex Distance has no effect when value is set below 0.1
Reproduction steps:
1. Open the attached “BugRepro” project
2. Open the “Assets/Scenes/DemoTrailsResolution.unity” Scene
3. In the Scene view, select the Wireframe Draw Mode from the Options toolbar
4. Enter the Play Mode
5. Observe the Scene view
Expected result: The two particle systems should have different trail resolutions
Actual result: Both particle systems have trails with the same resolution
Reproducible with: 2021.3.40f1, 2022.3.40f1, 6000.0.13f1
Reproducible on: Windows 11
Not reproducible on: No other environment tested

After further investigation, and with the help of Richard Kettlewell on the Unity forum, we figured out that the problem is not a Unity Bug after all, but indeed a framerate issue on our side. It could be “fixed” by disenabling v-sync for higher fps (or removing the internal fps cap on the actual project).
So it’s up to us to deal with how to work around this limitation.
Thank you very much for looking into this and setting us on the right track for finding a cause/solution.

Resolution Note:
As mentionned by Richard in this forum post https://discussions.unity.com/t/resolved-untiy-6-particle-trails-minimum-vertex-distance-has-no-effect-below-0-1-value/1491345, trail resolution is limited by frame rate. Only one point can be added per frame with particle trails and we have no plan to add built-in sub frame interpolation. Some API is available that can help implement this behavior (AddPosition)
