Would love to know this as well!

Hi, 

 I am trying to calibrate my Antilatency floor setup as well, did you use this video as a reference (https://youtu.be/C8MZ7g0Czrc)? If you did, did you just place the alt tracker on the floor to map out its origin or was the tracker on the camera rig to record the origin? Thank you!

Hi,

Yes, it is possible.

In our studio, we have a similar setup, where the markers are on the floor and the tracker is attached to the camera and it is facing downwards:

So in Aximmetry, after adding the tracked cam compound, you can navigate to the INPUTS control board.
Here you select ORIGIN 1:

In the pin values, next to Delta Head Transformation, you simply have to add either a +270 or a -90 rotation in the first field:

This will transform the rotation of the marker.

Please note, that your setup might be different, and you might need to adjust this setting, and/or add other rotations as well. You will also certainly need to add a transformation to the position values to compensate for the distance between the tracker and the rotation center.

I hope this helps.
