Runtime objects are not displayed when deployed to HoloLens 2

Cook, Craig 41

Hello,

I am following a learning path from the Build session on connecting Digital Twin data to the HoloLens 2 using Unity (https://mybuild.microsoft.com/sessions/815a692f-398b-4772-ac18-c021f5116757?source=schedule).

I have successfully created my resource, started the simulated data, and deployed the pre-configured 'CompletedScene' (with my azure resources) onto my HoloLens 2. I can see from the OperateSceneUI list that my simulated data is updating, however, the wind turbine models are not displayed.

When I make the turbine models 'Addressable', I get an error when running DeviceSimulation.sln.

Any recommendations would be greatly appreciated!

Thank you.

Hi @Cook, Craig ,
I'm sorry to hear that you are having this issue. I have a few questions that may help us figure out a solution:
There can be a slight delay before the models appear, how long did you wait to see if they show up?
If you click Play in Editor before you deploy, do they show up?
If you open "Completed Scene" located in Assets > Scenes in Unity and click Play, do the windmills show up?

Hi @Remy Jacks ,

Thanks for your message and really awesome demo at Build, this is why I'm so eager to have it working for myself!

I waited long enough that when I started the simulation, I could see the data being updated in the OperateSceneUI list on the HoloLens and it was also responding to the alert when triggered; just the windmills were not visible. I made sure that the location of the windmills matched the bing maps coordinates, and I still could not see the windmills show up.

I am confused because the windmills did appear in play-mode when I ran the exact same scene in the Unity window. I tried both 'CompletedScene' and 'MainScene' with my azure configurations.

Thanks,
Craig

I appreciate that. It was a really fun session to do at Build and a great project to work on!
Great to hear that you were successful at getting the data to pipe through correctly :)

I did see something kind of similar to this, but I feel like mine would show up after I clicked on them in the menu. Do you have your project saved in GitHub anywhere? If you can share a link to it we'll take a look.

@Remy Jacks ,

I've uploaded my project to GitHub here.

Yes I was very happy to see my data coming in correctly, but now the last missing piece is seeing those windmills on the HoloLens! After that, I look forward to adding new features like spatial anchors or mesh, and would be very interested to hear your thoughts about how they could be implemented.

Really appreciate your time looking into this.

Thanks,
Craig

Hey Craig,
It looks like your UI is displaying differently from what is in Github. I don't see the windmills in Completed Scene either. Have you been making any specific modifications to the project? There is a chance that while going through the tutorial, something got changed that isn't causing a crash, but is making things act strange.

If it's not too disruptive, you could re-clone the Github project, and then open Completed Scene, past your ADT URL into the ADTConnection prefab, create a new credential and connect that to the ADTTurbineAlertController.
If you do this, it should work fine. I know it's an inconvenience, but it may be difficult to determine why the UI looks different and why the Windmills aren't loading and easier to just start fresh and redo these final steps.

Hey @Remy Jacks ,

Thanks so much for your support on this..

I re-cloned your GitHub project and finally managed to deploy onto the HoloLens successfully!

Not exactly sure what specifically caused this issue, but I will keep playing around with the sandbox environment.

Take care!
Craig
