Motive is sending its tracking data in its native NatNet - Protocoll. The NatNetThree2OSC application receives the NatNet datastream, translates it into an OSC format and passes it on as an UDP-stream to a chosen IP address and port.

There are two different NatNet protocolls, and for each exists a different solution:

NatNet2 for Motive1.x NatNet3 for Motive2.x
