OptiTrack (asm_optitrack module)

OptiTrack support — the natnet_ros2 client, the PX4 external-vision fusion bridges, and the NatNet server emulator for Isaac Sim — ships as the standalone asm_optitrack module rather than in the AirStack trunk. To use it, add the module to your checkout:

airstack module add https://github.com/castacks/asm_optitrack --version <tag>

See AirStack Modules for how modules are declared, synced, and overlaid, and the module's own README for setup (including the host-side NatNet SDK download, which runs automatically as the module's host_setup hook).
