# Prepare Assets

### Rigid Body Calibration

Utilize one of a few simple methods to create a rigid body:

* Drag-select the rigid body's point cloud, right click the selected cluster, and select "Create Rigid Body" from the context menu.
* Navigate to the Rigid Bodies pane via the Create layout, and select either "Create from Visible" or "Create from Selected."
* Navigate to the Project pane and select the "Create Rigid Body" button from the top toolbar.

### Subject Calibration

*Note: Body tracking requires a license for Motive:Body.*

\
Select a markerset

Select a markerset template based on desired labeling and/or skeletal solve (e.g. broken toes and/or finger tracking). Note that markersets that include finger tracking are only compatible with Flex 13 or Prime Series cameras.

\
Apply markers

Once a markerset has been selected, a 3D marker placement guide will appear on the avatar beneath the menu. The model can be rotated to view particular marker placements in detail during marker application. Apply markers on the subject according to the guide.

\
Enter subject name

Enter a name for the subject, which will be used both to track the skeleton asset in the project manager and to generate unique marker labels during the kinematic labeling process.

\
One-click calibration

Instruct the subject to form a T-pose, then simply press "Create" to complete the subject calibration.

\
Multi-subject calibration

If there are numerous subjects requiring calibration in the same volume, you can drag-select the appropriate point cloud first, to ensure a successful calibration for each individual.
