OptiTrack Streaming Engine

Data Streaming pane

Utilize the OptiTrack Streaming Engine when streaming via Motive's free MotionBuilder plugin, 3ds Max Plugin, or any custom NatNet interface. To begin streaming, select "Broadcast Frame Data." Select which types of data (e.g. markers, rigid bodies, or skeletons) will be streamed, noting that some third party applications will only accept one type of data. Before you begin streaming, ensure that the network type and interface are consistent with the network you will be streaming over and the settings in the client application.

OptiTrack Streaming Engine: Streams marker, rigid body, or skeletal data via OptiTrack’s NatNet streaming engine.

Broadcast Frame Data: Default: Unchecked. Allows broadcasting the frame data. This box must be checked in order to start the streaming.


Network Interface

Sets the network address which the captured data is streamed to. When set to Loopback, the data is streamed within the computer, otherwise you can also choose the IP address specific networks.


Streaming Options

Stream Subject Prefix: When set to true, each marker label includes a subject prefix, which is the name of associated asset.

Stream Visual3D Compatible: Enables streaming to Visual3D. Normal streaming is not compatible with Visual3D, and this feature must be enabled in order to stream tracking data to Visual3D.

Stream Markers: Controls the streaming of individual marker locations over NatNet.

Stream Rigid Bodies: Controls the streaming of rigid body name, position, and orientation data over NatNet.

Stream Skeletons: Sets whether skeletons are streamed, if present.

Local Rigid Bodies: When enabled, the streamed position and rotation of each bone will be relative to its parent bones. Otherwise they will be global.

Skeleton as Rigid Body: Enables the streaming of skeleton segments as a series of rigid bodies.

Scale: Sets the scaling for streamed skeletal data.

Bone Naming Convention: Determines the bone naming convention for the streamed data among Motive, FBX, and BVH. It must match with the convention used in the streaming destination.


Advanced Network Options

Up Axis: Selects the upward axis in the streamed data. (Default: Y Axis).

Remote Trigger: Allows using the remote trigger for the streaming. (Default: False).

Type: Selects the mode of broadcast for NatNet. Valid options are: Multicast, Unicast. (Default: Multicast).

Command Port: Specifies the port to be used for negotiating the connection between the NatNet server and client. (Default: 1510).

Data Port: Specifies the port to be used for streaming data from the NatNet server to the client(s). (Default: 1511).

Local Interface: Specifies the network adapter to use for streaming NatNet data. Valid options are: Preferred (auto-select) (default), Local Loopback, and available network adapters by IP address.

Multicast interface: Specifies the multicast broadcast address. (Default: 239.255.42.99).

Note: When streaming to clients based on NatNet 2.0 or below, the default multicast address should be changed to 224.0.0.1 and the data port should be changed to 1001.
