Property categoryPivot

  • Editor-only property that displays and edits the pivot's CFrame relative to the instance, moving only the pivot and leaving the instance in place.
    • Not replicated
    • Not scriptable

Property categoryTransform

  • Editor-only property that reads and sets the world CFrame of the PVInstance's pivot, moving the entire instance when changed from the Studio Properties window.
