Constraints Pane

This page provides instructions for using the Constraints pane in Motive.


The reconstructed 3D markers that comprise an asset are known as constraints in Motive. The Constraints pane provides information and tools for working with solver constraints for all asset types: Rigid Bodies, Skeletons, and Trained Markersets.

Asset Selection

By default, the Constraints pane will display the constraints for the asset(s) selected in either the 3D Viewport or the Assets Pane. If none is selected, the pane will display the constraints for -All- the assets in the Live volume or in the TAKE, when in edit mode.

Customize Pane Columns

The default view of the Constraints pane includes the Constraint (or label), Type, and Color. Right click the column header to add or remove columns from the view.


The Constraint column displays the marker labels associated with an asset. When the Asset selection is set to -All-, the asset name is included as a prefix to the marker label.

  • Skeleton templates include pre-defined labels that correspond to the marker's location and easily import into other pipelines for biomechanical analysis or animation.

  • Rigid Bodies and Trained Markersets are auto-labeled with generic, sequential labels.


The MemberID column displays the unique ID value assigned to each constraint. Typically, this is the original order of the constraints.


There are four types of constraints:



The ActiveID column allows you to view and modify Active Marker ID values. Active ID values are automatically assigned during asset creation or when adding a marker, but this gives you a higher level of insight and control over the process.


Weight is the degree to which an individual constraint influences the 3D solve of an asset. Specifically, adjusting the weight tells the solver to prefer that marker when solving the asset data with less than an optimal amount of marker information. For example, the hands are weighted slightly higher for the baseline and core skeleton Marker Sets to preference the end effectors.

Editing this property is not typically recommended.

Modify Constraints

Add or Remove Constraints

Rename Constraints

To give a marker constraint a more meaningful name than the one auto-assigned when the asset is created, right-click the constraint name and select Rename from the context menu. Alternately, click twice on the constraint name to open the field for editing.

We recommend using the single asset view rather than -All- when relabeling markers from the Constraints pane.

You can also import a list of constraint properties, including names, for all asset types. See the section Export/Import Constraints, below and the page Constraints XML Files for more details.

Trained Markerset Copy and Paste

Import label names for Trained Markerset assets with a quick copy and paste of text. This is useful if you've already mapped out the asset, either during the design phase or while placing the markers.

  1. Copy the desired labels to the clipboard.

  2. Left click the Constraints Pane.

  3. Use Ctrl + V to paste the label names to the pane.

Please see the Labeling page for more information on using the Quick Labels tool.

Sort and Reorder Constraints

By default, the Constraints column sorts by the asset definition, or the order in which the markers were selected when the asset was created. Click the column header to sort the column alphabetically in ascending or descending order, then click again to return to the default.

There are two methods to change the order of the constraints in the internal asset definition:

  • Right-click a constraint label and select an option to move up or down from its present location.

  • Drag and drop labels into the desired order.

Reordering constraints helps to define custom marker sequences for manual labeling. Changes made to the order will also be reflected in the Labels pane.

Change Marker Color

Modify Constraints from the Properties Pane

You can modify the following additional constraint settings from the Properties pane when a constraint is selected in the Constraints pane.

  • Position and Rotation: adjust the x/y/z coordinates of the constraint, in respect to the local coordinate system of the corresponding asset or bone.

  • Marker Diameter: view or change the diameter of an individual marker.

  • Constraint Type: Motive assigns the constraint type during the auto-label process. The user should not need to adjust this property.

Export/Import Constraints

Exporting constraints makes an XML file containing the names, colors, marker stick definitions, and weights for manual editing. Importing reads the (.xml) files made when exporting. Generating constraints resets the asset back to the default state, if applicable.

Please see the page Constraints XML Files for more information on working with these files.
