Spatial Mapping Mesh is strange

Hi, I used SpatialMapping in HoloToolkit.
I scanned the room and saved it.
Then get .room file at device portal and convert to .obj file.
However When I import the obj file in unity editor, the file is very strange.
I don't know why this shape is strange.
I attached other picture in device portal 3D view. two models are made at same place.
Should I change some option in unity editor?

Please help me.
Thank you in advance!


  • Hey @kgil ,
    that indeed looks strange. Have you tried zooming out? Or double-clicking the GameObject?
    To help us trying to reproduce: What exactly are the steps you followed to download and import the mesh?

  • Hi @pstueven , Thank you for your response.
    I tried zooming out and double-clicking the object. But It was still strange.
    making mesh and importing step as follows:
    1. In Unity, I import HoloToolKit and load Scene ''SaveSpatialMapping"
    2. Make UI button for save room file.
    3. Build and Start app. after scanning the room, I click the button and room file is saved.
    4. I download the room file at Device Portal - File Explorer - RoamingState folder.
    5. Export .room to .obj file at Unity Editor.
    6. In Unity, import the obj file(mesh)

    I Think that plane made automatically. there are many strange planes in mesh. However I didn't use SpatialUnderstanding.
