Motive Rigid Body
Updated: 20 Jan 2026
Receive Mocap Data from Optitrack's Motive software.
Motive Rigid Body
Method #
This node let’s you receive Rigid Body data from Optitrack’s motive software. To receive skeleton data from this software, see Optitrack Mocap Skeleton. Rigid body’s in Motive are generally used to capture props or other objects that do not deform. This means they can be well represented by a singular transform. As the object is solid, moving it via one transform is sufficient to re-create the entire object’s movements accurately.
This node can also be used to receive transform data from labelled markers and marker sets.
A network connection must be made to the OptiTrack software which provides a stream of bone data from the suit. This is done via the Project Settings menu under the Tracking Protocols -> Motive section - use the “Motive” connection options.
Entering the IP of the target system can be unreliable in some cases, so we generally advise you leave the IP address blank. This will use the OptiTrack SDK to search for the OptiTrack system automatically, and is much more reliable at getting a connection. If that doesn’t work, it’s likely there is an issue with your network setup, as in that case the SDK itself can’t find it on the network at all.
