MRUK provides a rich set of utilities/tools on top of Scene API to perform common operations when building spatially-aware apps. This makes it quick and easy to program against the physical world and allows the developer to focus on what differentiates their app.

Version 203.0 Release Notes

What's New

  • The minimum supported version of Unity is now 6000.0.66f2.

    • What's Fixed

  • Fixed: when using Immersive Debugger, global mesh fails to render after updating the scan within the app.
  • Fixed: some internal usages of SceneLoadedEvent, RoomCreatedEvent, and RoomRemovedEvent were not correctly unsubscribed from. This caused a memory leak and in some cases resulted in MissingReferenceException when changing scenes.
  • Fixed NativeArray memory leak in AddBarycentricCoordinatesToMesh.

    • Deprecation

  • Scene Decorator is now deprecated.
