  • Image size from Unity packagae not what’s uploaded into Vuforia Hi all,

    I create in photoshop a rectangular 4.5cmx18cm Image. The 3d Object is also 4.5cmx18cm measured in Maya.

    When creating the Image database in Vuforia website I upload this image and enter 0.045cm width (Vuforia uses mtrs as default). I upload the Vuforia image from the unity package created from adding the target. Image and 3d Object scale in Unity are 1.

    When looking at these two in the editor, the 3d model looks tiny in comparison. The Image looking at Unity's editor shows...

  • Video background plane has wrong aspect ratio Hi there,

    I'm having this issue with the Vuforia video background plane.

    I'm on the new iPad Pro 11" with this wierd ratio 4.29:3 ?!??! (2388 x 1668 px).

    My problem is that my video render Background plane is somehow in 16:9 (with black borders on top and bottom).

    Xcode Log says:
    Cannot setMode to AR before Camera is initialized

    and

    VideoBackgroundConfig with screen size of zero received, skipping config step

    Unity: 2018.2.20.f1
    Vuforia: 7.5.26
    Xcode: 10.1
    iOS: 12.1


    Any ideas?...

  • Incorrect render of Graphics.Blit / CommandBuffer.Blit in VR Hey,

    I'm facing a strange issue when using Graphics.Blit / CommandBuffer.Blit in VR (Oculus). Under Unity 2017.4.10, everything looks fine. I have a camera that renders a layer offscreen on a RenderTexture with a lower resolution and then blit it on the scree. With Unity 2017.4.14 or above (2018.x), both eyes are offseted and the stereoscopic effect is messed. It's like the matrix used when rendering to a render texture have changed between these Unity versions.
    When using a Vive headset...

  • 2D Video Viewer with Tracking/Stabilization I'd like to create a 2D video viewer with tracking that changes the position of the video to mirror the location and orientation of the original camera using only the video as input.

    My concept was to use UMP (Universal Media Player) and attach it to a texture, but I'm unsure how I could get tracking data to move the camera.

    A video taken by someone who is walking down a street would result in the video moving horizontally, bumps in the video would cause the camera to shake but the...

  • 2018.3 update Oculus Go apk not working I updated my Unity version to 2018.3 and previous versions of Oculus Go apks now do not work. I get no compile error, but as soon as I try to open the program on the Go, there is only a black screen. The Unity logo doesn't pop up at all. I have to restart by holding the power button to get out of the frozen app. Has anyone run into this before?

    Thanks for your help!
  • how to anchor a gameObject position in Hololens Hi,
    I have two questions,
    1. When we load 3D object in hololens on careful observation it seems to be shaking from certain angle (corner). I want its corners to be anchored properly.
    2. When we load a 3D object in a space/room it doesn't retain its initial position if we move any other new room/space.
    How can i fix these issue. Please help, any suggestion.
