SpatialMapping produces strange map

runamuckrunamuck ✭
in Questions And Answers

I'm using the SpatialMapping Manager from the HoloToolkit in my app. When I launch the app and use this, I see the wireframe mesh begin to appear and it's very strange. It's producing column like structures in the middle of my room that aren't there. Additionally, when I look at the floor it's almost like the floor is transparent and I'm seeing structures under it being formed by the wireframe.

I only have this problem using the HoloLens unit itself. The emulator this script seems to work normally.

What is causing this?

    Can you give screenshots? There are some things to keep in mind:

    • If a person was standing when scanned, you'll see their 'mesh shadow' so to speak, until you get close enough to rescan that area.
    • Extra dark materials that don't reflect things well may produce oddities like hole sin the mesh.
    • Same for things that are reflective.

    Attached is a screenshot. The problem actually exhibits itself on very white carpet and walls. Take a look!

    Interesting, that is odd. I wonder if it would fix itself if you deleted the space or if it is reproducible in your environment. Though, before testing that, the mods may want you to submit the spatial mesh for debugging, they seem to always be interested when the spatial data behaves oddly.

    It's driving me kind of nuts. haha! I spent 8 hours over the weekend fiddling to see what I was doing wrong. But it works fine in the emulator so I have to believe it's something with my mesh on the device itself.

    Can you double-check that your main camera is at 0,0,0?

    If you tap around in the shell does the map seem right?

    What are the coordinates of your SpatialMapping prefab in your scene? Is it located in the root of your hierarchy?

    Hi @runamuck,
    Have you tried to delete the stored mesh on your device? To delete your space, start the 'Settings' app and then go to' Settings > Spaces', select your space and press 'Remove'. Let's see if generating a new mesh resoloves the issue.
