Motive:Body can export tracking data into FBX files for use in other 3D pipelines. There are two types of FBX files: Binary FBX and ASCII FBX.
When exporting tracking data onto the MotionBuilder in FBX file format, make sure the exported frame rate is supported in MotionBuilder (Mobu). In Mobu, there is a select set of playback frame rate that's supported, and rate of the exported FBX file must agree in order to playback the data properly.
Exported FBX files in ASCII format can contain reconstructed marker coordinate data as well as 6 Degree of Freedom data for each involved asset depending on the export setting configurations. ASCII files can also be opened and edited using text editor applications.
Export FBX Actors Includes FBX Actors in the exported file. Actor is a type of asset used in animation applications (e.g. MotionBuilder) to display imported motions and connect to a character. In order to animate exported actors, associated markers will need to be exported as well.
Marker Nulls Exports locations of each marker.
Export Skeleton Nulls Can only be exported when solved data is recorded for exported skeleton assets. Exports 6 Degree of Freedom data for every bone segment in selected skeletons.
Rigid Body Nulls Can only be exported when solved data is recorded for exported rigid body assets. Exports 6 Degree of Freedom data for selected rigid bodies. Orientation axes are displayed on the geometrical center of each rigid body.
Optical Marker Name Space Overrides the default name spaces, C3D.
Marker Name Separator Choose ":" or "_" for marker name separator. The name separator will be used to separate the asset name and the corresponding marker name when exporting the data (e.g. AssetName:MarkerLabel or AssetName_MarkerLabel). When exporting to Autodesk Motion Builder, use "_" as the separator.
Units Set the unit in exported files.
Markers Export each marker coordinates.
Unlabeled Markers Includes unlabeled markers.
Binary FBX files are more compact than ASCII FBX files. Reconstructed 3D marker data is not included within this file type, but selected skeletons are exported by saving corresponding joint angles and segment lengths. For rigid bodies, positions and orientations at the defined rigid body origin are exported.
Skeleton Nulls Can only be exported when solved data is recorded for exported skeleton assets. Exports 6 Degree of Freedom data for every bone segment in selected skeletons.
Skeleton Names Names of skeleton assets that will be exported onto the FBX file. By default, all skeletons are exported.
Units Sets the unit for exported segment lengths.
