Best Of

I downloaded the files from git hub.
I'm working with the SharedMixedRealityLand.scene that is completely built.
I can get it deployed to both hololens and a samsung odyssey.
Im using Unity 2017.2.0p2-MRTP5

The sharing and sessions do not show up in the list for some reason.

In the Hololens:
host id 1
isclient false
isserver true
isrunning true
anchor name is blank
anchor created false

Errors with spatial mapping:
null reference exception on spatial mapping observer.update()

Here is my Update method on SpatialMappingObserver

private void Update()
{
// Only do processing if the observer is running.
if (ObserverState == ObserverStates.Running)
{
// If we don't have mesh creation in flight, but we could schedule mesh creation, do so.
if (surfaceWorkOutstanding == false && surfaceWorkQueue.Count > 0)
{
// Pop the SurfaceData off the queue. A more sophisticated algorithm could prioritize
// the queue based on distance to the user or some other metric.
SurfaceData surfaceData = surfaceWorkQueue.Dequeue();

                // If RequestMeshAsync succeeds, then we have successfully scheduled mesh creation.
                surfaceWorkOutstanding = observer.RequestMeshAsync(surfaceData, SurfaceObserver_OnDataReady);
            }
            // If we don't have any other work to do, and enough time has passed since the previous
            // update request, request updates for the spatial mapping data.
            else if (surfaceWorkOutstanding == false && (Time.time - updateTime) >= TimeBetweenUpdates)
            {
                observer.Update(SurfaceObserver_OnSurfaceChanged);
                updateTime = Time.time;
            }
        }
    }

Also what is the trick to get code clocks to appear correctly on this forum?

Any Ideas what is wrong? I have made no code changes. Did i download a bad build?

For those of you developing VR experiences for the new Windows Mixed Reality immersive headsets, we have an important message: if you stay in the Windows Insider Fast ring, beginning October 10, 2017 you may begin to receive RS4 builds, which will not be the most stable builds for mixed reality development. To continue mixed reality development uninterrupted, please switch your Insider settings to receive "just fixes, apps, and drivers" without getting a new Windows build from the "Windows Insider Release Preview" ring.

Instructions for switching:
1. Open Windows Settings
2. Select "Update & Security"
3. Select "Windows Insider Program"
4. In the "What kind of content would you like to receive?" drop-down menu, select "Just fixes, apps, and drivers"
5. In the "What pace do you want to get new builds?" drop-down menu, select "Windows Insider Release Preview"
