Tracked Billboard issue

Studio Operators Composer Camera Tracking

 
OK, this one is driving me crazy. I am sure the answer should be simple.
When I create a mixed cam project and try to track billboard it does strange things. When the tracking is off everything seems OK. I turn on Optical tracking just for the sake of it and It also works. At least I still can see the billboard. But when I turn on Antilatency Tracker it flips the billboard and messes the scale.
Trackers are calibrated, I can track position of meshes(with offset), no problem, but when it comes to billboards it just doesn't work.
Sure I am missing something. What do you think?

Hi Andrew,

Sadly, I can not see the video, it is broken or removed according to Facebook.

Note that the billboard tracking system does not move in Y-axis: https://aximmetry.com/learn/tutorials/for-studio-operators/setting-up-virtual-sets-with-tracked-cameras/#automatic-positioning-of-the-billboard


Did you use the Aximmetry Camera Calibrator to calibrate the trackers? Or for example, you changed values in Manage Devices?

Warmest regards,

Hey, thanks for the respond. The point is that the Lock to camera does not affect the position of the billboar when i use Antilatency tracker. It does not react to it. I calibrate the tracker in the Manage devices section, I set the three points. 

Her's the link to the video.

Hi,

It seems the tracking position is not correct. I am guessing halfway in that video you turned on Auto PositionTracking. If you needed an offset in the flow editor or in the camera compound for a mesh to show up at the correct place, then you should incorporate that offset into the Manage Devices settings.
Also, are you using Antilatency to track the camera? Do they have different calibrations in the Antilatency Service software for the trackers?

And is that capsule a Player Start Actor? If so, you could:

  • A) Set the player model to an invisible one:
    • Go to Edit / Project Settings / Project / Maps & Modes / Default Modes
    • Create a new game mode by pressing the + button (Give it a name and press OK)
    • The new game mode should be selected as the Default GameMode
    • Open the Selected GameMode section
    • Change the Default Pawn Class to None
  • B) Move the PlayerStart outside of the scene. In this case, the gray sphere will spawn in an invisible area. (Its position is indifferent for Aximmetry.)

I am having the very same issue which is shown his video. Please tell us which settings is likely to cause this.
