Main Page → Motive Documentation → Data Export → Data Export: FBX

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.

Notes for MotionBuilder Users

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.

Mobu supported playback framerates.

FBX ASCII

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.

FBX ASCII Export Options
Options	Description
Frame Rate	Number of samples included per every second of exported data.
Start Frame	Start frame of the exported data. You can either set it to the recorded first frame of the exported Take or to the start of the working range, or scope range, as configured under the Control Deck or in the Graph View pane.
End Frame	End frame of the exported data. You can either set it to the recorded end frame of the exported Take or to the end of the working range, or scope range, as configured under the Control Deck of in the Graph View pane.
Scale	Apply scaling to the exported tracking data.
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.
Use Timecode	Includes timecode.
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.
Export Fingertips	Includes virtual reconstructions at the finger tips. Available only with skeletons that support finger tracking (e.g. Baseline + 11 Additional Markers + Fingers (54))

FBX Binary

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.

FBX Binary Export Options
Options	Descriptions
Use Timecode	Includes timecode.
Frame Rate	Number of samples included per every second of exported data.
Start Frame	Start frame of the exported data. You can either set it to the recorded first frame of the exported Take or to the start of the working range, or scope range, as configured under the Control Deck or in the Graph View pane.
End Frame	End frame of the exported data. You can either set it to the recorded end frame of the exported Take or to the end of the working range, or scope range, as configured under the Control Deck of in the Graph View pane.
Scale	Apply scaling to the exported tracking data.
Export Skeletons	Export skeleton nulls. Please note that the solved data must be recorded for skeleton bone tracking data to be exported. It exports 6 Degree of Freedom data for every bone segment in selected skeletons.
Marker Nulls	Exports locations of each marker.
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.
Units	Sets the unit for exported segment lengths.
Unlabeled Markers	Includes unlabeled markers.
Export Fingertips	Includes virtual reconstructions at the finger tips. Available only with skeletons that support finger tracking (e.g. Baseline + 11 Additional Markers + Fingers (54))
