A camera plugin for AUTODESK MotionBuilder  2014-2018 (32/64 bit)  and Mo-SYS camera tracking system StarTracker.



StarTrackCam connects camera tracking data delivered in real-time from the MO-SYS camera tracking system StarTracker to AUTODESK MotionBuilder in order to support real-time previs or virtual production. Camera position, orientation and zoom/focus/iris encoder values are delivered to the MotionBuilder PC via serial connection and used to control a virtual camera in the realtime render engine of MotionBuilder. Virtual sets created by generic modelling tools such as AUTODESK Maya or 3D Studio Max can be merged with the live camera data by converting the sets to Autodesk FBX and importing them in MotionBuilder.

You need a valid AUTODESK MotionBuilder license installed under Microsoft Windows 7/8/10 64 bit  workstation or laptop and a StarTracker system to benefit from the plugin. Connect the MO-SYS gateway box with a RS422 cable to the MotionBuilder PC or use a Serial-USB-Converter on the PC/Laptop side in order to make the camera tracking data available in AUTODESK MotionBuilder. BTW, if you own a MO-SYS gateway box and some of the  tracking equipment encoded by the T4 protocol of MO-SYS, you can still benefit from this plugin since it makes all properties  encoded as T4 protocol properties available in AUTODESK Motionbuilder as input animation channels.
