# Data Export: FBX
Motive 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.
### 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.
  
| Options | Description |
| ------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| Units | Set the unit in exported files. |
| Exported 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. |
| Export Markers | Export each marker coordinates. |
| Export Unlabeled Markers | Includes unlabeled markers. |
| Export Skeleton Nulls | Can only be exported when JT data is recorded. Exports 6 Degree of Freedom data for every bone segment in selected skeletons. |
| Export Rigid Body Nulls | Exports 6 Degree of Freedom data for selected rigid bodies. Orientation axes are displayed on the geometrical center of each rigid body. |
| Export Marker Nulls | Exports locations of each marker. |
| 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). |
### 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.
| Options | Descriptions |
| ----------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Units | Sets the unit for exported segment lengths. |
| Export FBX Skeleton | Includes skeleton Actors in exported FBX file. Actor is an asset used in animation applications (e.g. MotionBuilder) to display the imported motion and connect to a character. |
| Export Rigid Body Nulls | Exports Rigid Body pivot points for position and orientation of rigid bodies. |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.optitrack.com/v1.1/motive-documentation/data-export/data-export-fbx.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
