NatNet Driver
このコンテンツはまだ日本語訳がありません。
The NatNet Driver receives real-time tracking data from OptiTrack systems using the NatNet protocol. NatNet is a widely used motion-capture streaming API that transmits rigid body positions, markers, skeletons, and metadata over a network for use in virtual production, xR, and real-time environments.
The driver allows Disguise to subscribe to an OptiTrack server and stream incoming tracking data directly into your project. Most setups require only the correct multicast address and data port, while additional connection information helps verify communication and server status.
Use the NatNet Driver when integrating OptiTrack motion-capture data into Disguise for virtual production, xR workflows, or real-time automation. The driver streams rigid body tracking data directly from Motive, allowing virtual objects, cameras, characters, or environments to follow real-world motion with high precision.
This driver is especially useful when:
- Bringing OptiTrack rigid body tracking into virtual production or xR scenes.
- Driving virtual cameras using motion-capture camera rigs.
- Tracking performers, props, or handheld objects for real-time interaction.
- Synchronising physical motion with 3D environments or media playback.
- Testing or validating NatNet streaming using Motive’s live mocap data.
- Monitoring server connection details (versions, ports, discovery status) to ensure stable network communication.
As NatNet supports high-frequency, low-latency data streaming, this driver is well suited for fast, precise tracking where real-world motion must match virtual content accurately.
Driver Properties
Section titled “Driver Properties”
Multicast Address
Section titled “Multicast Address”Specifies the multicast group address from which NatNet tracking data is received.
This should match the multicast address set in your OptiTrack Motive configuration.
Data Port
Section titled “Data Port”The UDP port on which NatNet sends its motion data stream.
Ensure this matches the “Data Port” configured in Motive.
Connection Info
Section titled “Connection Info”This section displays diagnostic information about the connection between Disguise and the NatNet server.
- Command Port — The port used for command/control communication with the NatNet server.
- Server Name — The name of the connected Motive/OptiTrack server.
- Server Version — The NatNet server version currently in use.
- SDK Version — The NatNet SDK version supported by the driver.
- Start Server Discovery — Initiates a scan to automatically detect available NatNet servers on the network.
Use this information to verify that Disguise is correctly connected to your OptiTrack system and running compatible versions of Motive/NatNet.
