Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

Holograms 101 - Chapter 6 - Spatial Mapping

Good afternoon,

I have downloaded the last and most updated Origami project but I have an error when I add the Spatial Mapping on step 6.

It builds and deploys without any problems to the HoloLens device, but when the App starts running, the Origami object is gone and all I can see is the wiring of the spatial mapping. Does anybody have an idea of what might be happening?

  • Hello Patrick,

    Yes, that was it. I moved to a "cleaner" room and problem solved. I am running on the actual device, by the way.

    Thank you.

  • I had the same problem. Turns out the newest unity project files uses spatial mapping manager and observer scripts instead of on the prefab "spatial mapping". Step six is looking for that prefab to have a script/class called spatial mapping. I copied over the cs script called "spatial mapping" from the old origami project into and attached it to the prefab. After that everything works fine. Though the manager and observer become redundant once you do this. The tap to place script will start working once it sees this class though.
