LightAct offers 2 ways of connection with the OptiTrack server. The first type is Auto-detect where LightAct will find OptiTrack servers on the network so you can choose one of them in Discovered servers dropdown menu. The second option is to manually set the server parameters if Auto-detect is unchecked.
Good to know: OptiTrack integration relies on NatNet SDK, which is created and maintained by OptiTrack.
