A Motive Body license 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.
If there is a non-standard frame rate selected that is not supported, the closest supported frame rate is applied.
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
Frame Rate
Number of samples included per every second of exported data.
Start Frame
End Frame
Scale
Apply scaling to the exported tracking data.
Units
Set the unit in exported files.
Use Timecode
Includes timecode.
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.
Optical Marker Name Space
Overrides the default name spaces for the optical markers.
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.
Markers
Export each marker coordinates.
Unlabeled Markers
Includes unlabeled markers.
Calculated Marker Positions
Export asset's constraint marker positions as the optical marker data.
Interpolated Fingertips
Includes virtual reconstructions at the finger tips. Available only with Skeletons that support finger tracking.
Marker Nulls
Exports locations of each marker.
Export Skeleton Nulls
Rigid Body Nulls
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
Frame Rate
Number of samples included per every second of exported data.
Start Frame
End Frame
Scale
Apply scaling to the exported tracking data.
Units
Sets the unit for exported segment lengths.
Use Timecode
Includes timecode.
Export Skeletons
Skeleton Names
Names of Skeletons that will be exported into the FBX binary file.
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.
Rigid Body Nulls
Rigid Body Names
Names of the Rigid Bodies to export into the FBX binary file as 6 DoF nulls.
Marker Nulls
Exports locations of each marker.
