Just to inform the devs:
The component “VisionOS Sorting Group” is broken in PolySpatial version 2.0.4 when used with Unity 6.0.27. Pressing the “+” button on the list does nothing.
I had to revert to PolySpatial version 2.0.0-pre.11, where it works correctly.
I can’t reproduce this. With a new project using 6000.0.27f1 and PolySpatial 2.0.4, I’m able to add an instance of VisionOS Sorting Group and add new entries to the Renderers list using the + button as expected. They start out collapsed, which is annoying, but they work otherwise.
We did change the API of the Renderers property in 2.0.4 (from a List to an ObservableList, and the properties changed from camelCase to PascalCase), which makes me wonder if the older data is getting in the way. You might try removing the VisionOSSortingGroup component entirely and readding it, if you haven’t already. If that doesn’t work, you can submit a bug report with a repro case (and let us know the incident number: IN-#####), and we can look into it further.
