To enable the Pulsars to be tracked, you must create smart objects in Evoke for them.

Each smart object is assigned a marker pattern, which is sent to the linked Pulsar.

When you select a smart object, its linked Pulsar device is also selected and its status lights display a selection sequence. The object is also selected in the **3D View**.

In the **System** panel, the Pulsar connection icons on the linked Pulsars turn green as they are assigned patterns by the smart objects.

> ℹ️ **Note**   
> ℹ️ When smart objects are created, some cluster parameters, such as Enabled and Marker Pattern become read only, as these are managed by smart objects.

When you create a smart object, you can select the appropriate template for your smart object and you must link the smart object to the relevant Pulsar(s) to enable tracking.

In addition to the Pulsar template, templates are supplied for the Vicon headset mount for supported headsets: the Oculus Rift, HP Reverb and HTC Vive. The templates are pre-configured with sections corresponding to the Pulsar slots at the top and front of the headset, and the smart object origin set to the optical origin of the headset. Templates for the Vicon hat and backstrap are also supplied.

If required, you can create additional templates (see [Use smart object templates](https://vicon-help.atlassian.net/wiki/spaces/Evoke18/pages/397968574)).

    **To create a smart object:**


1. In the **Tracking Setup** panel, in the **Smart Object** field, enter a unique name for the new smart object, ensure that the required template is selected and then click the **Create** button.
  The new smart object is displayed at the top of the **Smart Objects** section in the **Tracking** panel.
  It has the name you entered and is automatically assigned a unique pattern. Because no device is associated with it yet, a caution icon (yellow triangle) and unlinked Pulsar icon are displayed next to it. To enable tracking, you must link the smart object to a Pulsar.
2. In the **Properties** pane, go to the **Smart Clusters** section and in the **Device** field, select the Pulsar that you want to associate with this smart object.If you are using the template supplied for the Vicon headset mount for a supported headset, you must select a device for both Pulsars.
3. Enter the remaining details for the smart object (color, mesh, etc).   
The mesh is an FBX file with the mesh skinned to a Root bone. You can use the installed meshes that are displayed when you click on the **Mesh** list, or your own FBX files, saved to *C:\Users\Public\Documents\Vicon\PropMeshes*.

### 
    Rename smart objects


You may need to rename smart objects, for example, to match their intended location (eg, `Green_LeftHand` or `Red_RightFoot`). 

You can rename smart objects in the **Tracking Setup** panel.


    **To rename smart objects:**


1. In the tree at the top of the **Tracking** panel, do one of the following:
  - Double-click the smart object; or
  - Right-click the smart object and then select **Rename**; or
  - Select the smart object and press F2.
2. Enter a unique new name for the smart object.

## Confirm smart object tracking and labeling

After you have created the required smart objects, make sure they're displayed in the **3D View**, with labels matching the smart object names.

Cluster and smart object settings are stored in the *System* file. Its default location is: *C:\Users\Public\Documents\Vicon\Evoke1.#\LastRun\*userName*\LastRun.System*

Object settings are stored in the *Subjects* file. Its default location is: *C:\Users\Public\Documents\Vicon\Evoke1.#\LastRun\*userName*\Subjects.mcp*

Settings are auto-saved periodically when changes are made as well as when you exit Evoke.

> ✅ ** Tip**  
> ✅ If you need to find out which physical Pulsar is linked to its representation in Evoke, press the Pulsar's power button. It is then selected in Evoke and its status light blinks to indicate that it's currently selected.

You can reassign the patterns on the smart objects if you want to customize them further. For more information, see [Reassign smart object patterns](https://vicon-help.atlassian.net/wiki/spaces/Evoke18/pages/397968527).
