Unable to complete Academy Tutorial 240 Chapter 3

I am using the HoloLens emulator and a second computer that is running SharingServices on my local network. The SharingServices computer registers the connection once the app launches. The debug window shows "Session Join Succeeded" followed by "User joining session: 390260390". I am using the latest code available from the HoloLens GitHub site. I have replaced the HologramPlacement.cs with the changes published in the tutorial.

I get the following error message:
NullReferenceException: Object reference not set to an instance of an object.
at ImportExportAnchorManager.InitRoomApi()
at ImportExportAnchorManager.Update()
at ImportExportAnchorManager.$Invoke28(Int64 instance, Int64* args)
at UnityEngine.Internal.$MethodUtility.InvokeMethod(Int64 instance, Int64* args, IntPtr method)
(Filename: Line: 0)

Additionally, the hologram does not interact with the wire frame within the HoloLens emulator. I can move the hologram around the room but it passes through all surfaces.

How can I resolve this issue?



  • Hi @AnthonyG,
    I recently updated the course to work with Unity 5.5 and also updated the Sharing service to the latest version found in the HoloToolkit. This should help make sharing a little easier. Please download the newer version of the course and upgrade to Unity 5.5 to give it a try.
