WHAT IS MOTIVE

Motive software pairs with OptiTrack cameras to track and capture the motion of small retroreflective markers attached to people and objects, and delivers real-time motion data with industry-leading accuracy.

Motive offers simple setup, supports larger volumes and produces clean data. Tracking data is used in numerous ways from robotics and movement sciences to video game animation, cinematic virtual production and location-based virtual reality.

WHAT'S NEW?

· ActiveIO：Motive 3.5 adds support for ActiveIO, OptiTrack's next-generation active tracking platform. ActiveIO devices combine uniquely identifiable active markers with bidirectional communication, automatic firmware updates, onboard IMU data, GPIO support, persistent device settings, and real-time device status information. For large-scale VR, simulation, ICVFX, stage tracking, and entertainment environments, ActiveIO makes active tracking easier to deploy, monitor, and manage.

·  PrimeX260 Cameras：Adds support for the PrimeX 260, PrimeX 260W, and SlimX 260. With 26 MP sensors, the 260 series is built for premium tracking systems where maximum resolution, accuracy, and large-volume performance are required.

· SlimX22：Added support for SlimX 22, a compact high-speed camera designed for active tracking workflows. SlimX 22 extends the SlimX family with a focused active-only option for applications that prioritize speed, scale, and efficient deployment.

· Deadband Filter：The new rigid body deadband filter allows Motive to hold a rigid body perfectly still once motion falls below a defined threshold. This is especially useful for ICVFX, broadcast, camera tracking, and other workflows where tiny tracking fluctuations can become visible when projected over long distances.

· New Streaming Types：

   Raw IMU data (inertial measurement unit) – enables client-side sensor fusion workflows.

   GPIO data (General Purpose Input/Output) – allows button presses, triggers, and sensor inputs from ActiveIO devices to be sent to game engines or client applications.

   Anchor Markers – helps NatNet clients remotely monitor system health and calibration stability. A new example client for how to do this is included with NatNet 4.5.

· OpenUSD Export：Export animation files to OpenUSD format for importing into game engines (e.g. Unreal) and other workflows like the NVIDIA Omniverse.

· STL Attached Geometries：Users can now attach STL geometry files to rigid bodies for improved visualization in engineering workflows.

· Passive or Active Only Modes：Added back the ability to have Passive Only and Active Only markers.

· OpenCV Calibration Representation：Add a new intrinsic representation in MCAL files that makes working with OpenCV easier to do.

· Unlabeled Markers Visibility Toggle：Added the ability to toggle the visibility of unlabeled markers in the 3D view.

The release of Motive 3.5 is more than just a software update—it is a redefinition of spatial computing and precision tracking. Upgrade now and experience the power of evolution.
