![]() I’m planning to capture as much as I can in this 2m square office, plus a couple of metres of narrow landing just outside the office door. All I have to do to is plug the supplied router into my machines, put the suit on, open the software, perform a quick range of motion, and I’m ready to capture. Luckily, I don’t need any of this with an inertial mocap system. I also don’t have a big empty room with high ceilings I can use for my capture volume. I’ll be doing the motion capture at home, so I don’t really want to run metres of network cables around the house, or drill holes in the walls and put up scaffolding and tripods to mount cameras. So, does this mean the Xsens MVN system is the best motion capture system available today? Do I recommend it over any other system? Well, for this project, yes. This skeleton animation can then be recorded, as well as streamed in to MotionBuilder and other software like Unreal or Unity for real-time rendering and preview. ![]() The software converts the individual tracker data in to skeleton motion in real-time. The data from the sensors is then transmitted to MVN Animate software over Wi-Fi. These sensors track the movements of the performer’s hips, chest, head, shoulders, arms, hands, legs and feet. Instead, the performer wears the usual tight fitting all-in-one Lycra mocap suit, but this one contains 17 inertial motion trackers zipped into pockets on each of the major parts of the body. The system can be used in almost any situation, indoors and outdoors, and even under clothing because it doesn’t use cameras and reflective markers like an optical system. The Xsens MVN Link system is a portable full-body inertial motion capture system. You might have seen these systems being used in a recent Ted Talk by Doug Robel from Digital Domain, or in Image Engin‘s Breakdown of their work on The Mandalorian…or maybe even my personal favourite, Paul. So, for this project, I’m using the Xsens MVN Link Inertial Motion Capture System. And to do that, we’re going to need a motion capture system. Try to refresh your XSens Avatar.To start this series of tutorials recreating the Lobby Shootout from The Matrix, we’re going to need some motion capture. Another reason could be a bug inside of the software itself. In case the calibration is not working, there might be something wrong with a sensor in the suit. Now your bodypack should be recognizable for life streaming. And then in the MVN Animate Software go to Preferences/Soft Acces Point -–> Disable OBR. Connect the bodypack with USB to your computer. If your bodyback isn’t being recognized for live streaming, it’s probably caused by the OBR mode still being enabled in the bodypack. Please notify us about the changes you have made. Just drag the sensor you want to use into the sensor you want to have replaced. If it’s sensor that doesn’t allow a direct replacement, like a knee or an elbow, the suit is unusable and you have to contact us immediately. If it’s a single sensor, like ‹pelvis›, ’stern›, ‹head›, ‹right hand›, ‹left hand› and also the ‹right -‹ or ‹left foot› you can try to swap it with the ‹prop›. There’s a great description on how to import OBR here Troubleshooting Sensor not responding There’s a great description on how to calibrate OBR here. Configure if you’re going to be moving on uneven ground. OBR allows you to capture your movements anywhere. There is a good documentation on how to set up the Xsens Suit with Unity here. There is a good documentation on how to set up the Xsens Suit with Unreal here Unity Engine Then just follow the procedure depicted in this video Unreal Engine Under «Plugins, Integrations and Sychronizations» you can download the latest Maya Plugin. There are working realtime integrations with Maya, Motionbuilder, Unity and Unreal Engine. Life Performances don’t need to be limited to the Xsens Software. You should be able to start live recording now. These are the sensor IDs and they’re roles by default: It is very important though to inform us about the changes you’ve made to the sensor IDs role. This will lead the ID of the sensor to be representing a different body part than it was originally configured to be. In that case you might want to swap them with the another sensor. Now and then a sensor might be malfunctioning. The Sensors are connected to cable whips that should be contained in the same bag as the sensors. ![]() Lower Body: 1 x Pelvis, 3 x Right Leg, 3 x Left Leg Upper Body: 1 x Head, 1 x Stern, 3 x Left Shoulder, 1 x Left Hand, 3 x Right Shoulder, 1 x Right Hand These 17 are essential to get the capturing process started at all: Bottom row, ltr: upper body cable whip, lower body cable whip, cable whip to connect prop in conjunction with a body part. Top row, ltr: upper body sensors, lower body sensors, prop.
