Data Export: USD

Configuration options for exporting data to the USD format.

Overview

Universal Scene Description, or OpenUSD, is an open source framework developed by Pixar Animation Studios that provides an efficient method for working with and compiling 3D content across applications. Export tracking data from Motive into the USD format for use with other applications, such as Blender, Unreal Engine, Godot, CAD systems, and other design software.

Please visit the Alliance for OpenUSD for more information on the OpenUSD format and its various uses.

The USD export option is available with the Motive Body license only.

General Export Options

The general export options set the basic parameters of the export. To change any of these parameters, click the button to the right of the option.

Frame Rate

The number of samples included per second of exported data. The default option is to use the current frame rate. Click the ellipses to the right to set a custom frame rate.

Start Frame

Starting frame of the exported data. Set to one of the following:

• The recorded first frame of the exported Take (the default option).

• The start of the working range (or scope range) as configured under the Control Deck in the Graph View pane.

• Custom to enter a specific frame number.

End Frame

End frame of the exported data. Set to one of the following:

• The recorded end frame of the exported Take (the default option).

• The end of the working range (or scope range) as configured under the Control Deck in the Graph View pane.

• Custom to enter a specific frame number.

Scale

Apply scaling to the coordinates/distance of tracked assets in the exported tracking data.

Units

Set the measurement units to use for exported data.

Specific Export Options

Specific options determine which data to include in the export.

Assets must be solved and enabled in Motive to include in the USD export.

Export Skeletons

Enables the export of skeleton data. Skeleton assets must be solved and enabled in Motive to be included in the export.

Skeleton Names

Select the specific skeletons to include in the export. Note that the skeleton must be solved and enabled in Motive to be included in the export.

• All Skeletons exports all enabled skeletons included in the Take. This is the default option.

• Selected Skeletons exports only the skeletons selected from either the Assets pane or the 3D viewport in Motive.

• Custom allows you to specify which of the skeletons included in the Take to export.

This option is only available when Export Skeletons is enabled.

Bone Naming Convention

The Bone Naming Convention determines the format to use for exported Skeleton data so each segment can be properly recognized by the client application. The naming convention must match the format used in the client application.

• Motive: Uses the standard Motive bone naming convention.

• FBX: Used for importing into Autodesk pipelines, such as MotionBuilder or Maya.

• UnrealEngine: Used for importing into UnrealEngine.

Export Rigid Bodies

Enables the export of Rigid Bodies from the selected Take. Rigid Body assets must be solved and enabled in Motive to be included in the export.

Rigid Body Names

Select the specific Rigid Bodies to include in the export. Note that the Rigid Body must be solved and enabled in Motive to be included in the export.

• All Rigid Bodies exports all solved and enabled Rigid Bodies included in the Take. This is the default option.

• Selected Rigid Bodies exports only the Rigid Bodies selected in the Assets pane or the 3D Viewport in Motive.

• Custom allows you to specify which of the Rigid Bodies included in the Take to export.

This option is only available when Export Rigid Bodies is enabled.

Export Markersets

Enables the export of Trained Markerset data from the selected Take. Trained Markerset assets must be solved and enabled in Motive to be included in the export.

Markerset Names

Select the specific Trained Markersets to include in the export. Note that the Trained Markerset must be solved and enabled in Motive to be included in the export.

• All Markersets exports all enabled Trained Markersets included in the Take. This is the default option.

• Selected Markersets exports only the Trained Markersets selected in the Assets pane or the 3D Viewport in Motive.

• Custom allows you to specify which of the Trained Markersets included in the Take to export.

This option is only available when Export Markersets is enabled.

Export Markers

Enables the export of labeled marker data from the selected Take.

Export Unlabeled Markers

Enables the export of unlabeled marker data from the selected Take.

Exclude Fingers

Enables the export of skeleton data without including data for the fingers.

This option is only available when Export Skeletons is enabled.

Cameras

Enables the export of 2D camera data. Select All Cameras or Color Cameras from the dropdown list.

Skeletal Mesh

Enables the export of the Motive skeletal mesh along with the skeleton data.

Z-up Skeleton

Enables the export of Skeleton data using the Z-up coordinate system.
