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.

Limit Scanning By Time in Spatial Mapping

This is with regards to the Spatial Mapping tutorial - Holograms 230 .

I am running the app exactly as specified in the tutorial. On Place Space Manager on the Spatial Processing Game Object, Limit Scanning by Time is set to true and Scan time is set to 10 seconds. I expected all spatial scanning to stop after the projector and posters had been placed in the room because the surface observer is only restarted if the scanning time has not been reached or there were not enough floors and walls to place the holograms on.
However, I find that the scanning continues and I can move from room to room with new wall surfaces rendered in blue lines.
What am I missing?

Apologies if this is fairly obvious to most. I am a newbie to both HoloLens and Unity and have been finding spatial mapping a challenge to understand.

  • @psi is the "Draw Visual Meshes" checkbox checked on the Spatial Mapping Manager?

    if so you probably want to uncheck it so that it will not be turned on by default.

  • Thank you HoloSheep. I am wondering why I see surfaces being rendered in new rooms I enter after 10 seconds and the space collection objects have been placed? Why does it continue scanning surfaces.
    Does the Hololens keep track of rooms you have been in in the past?

  • Thank you! Now I get it :)
