    Hi all. I have problem with the app using Spatial Mapping. In the grid, sometimes holes on the walls, a grid on air in space. With what it can be connected?

    Hello @VladimirAnokhin

    From what I can tell you're generating the spatial map correctly, if you see holes in walls and such make sure your environment is well lit and the surfaces are not dark colors. From my experience, Hololenses can have trouble finding surfaces that are not well lit or are very dark colors. As for the grids in air, was there previously an object there and it's just not disappearing? Or is this like a wall completely out of place?

    If you can post some screenshots of these visualizations, maybe we can offer some better targeted.

    Strange, but the problem somehow decided by itself. But there was a new, with the movement in the Hololens the grid with the placed objects on it begins to shift together with the glasses, then the space is stabilized. What could be the problem?

    That sounds like the Hololens briefly had trouble establishing tracking so it was not aware that it was moving. Once it realized there was movement it stabilized the environment to the new position. Does it consistently feel "Swimmy" or wobbly? Or does it only do it for a brief moment and then snap back to position?

    Shaking and movement occurs when we move or turn our heads. Especially when going from room to room. But when moving, the displacement goes literally for a couple of seconds, then the objects return to their places. But they are shaking. Plus, objects sometimes seem to "fall through" into the wall.

    On that video you can see how grid shifts.
    You can also see how objects are in the wall. Here it is not very visible, very often the objects completely go to the wall.
    FPS stable 60 without video recording.This is not the best video example, usually the effect is even stronger
