Motive (1.7+) uses a right-handed Y-up coordinate system. However, coordinate systems used in client applications may not always agree with the convention used in Motive. In this case, the coordinate system in streamed data needs to be modified to a compatible convention. For client applications with a different ground plane definition, Up Axis can be changed under Advanced Network Settings. For compatibility with left-handed coordinate systems, the simplest method is to rotate the capture volume 180 degrees on the Y axis when defining the ground plane during Calibration.
