To get good tracking performance from different viewpoints or under occlusion, you may need to attach multiple Pulsar clusters or extra markers to a single rigid object. In particular, if you are using VR headsets and/or guns or similar props, you may benefit from the better rotational stability and/or occlusion resistance offered by combining multiple Pulsar clusters.


    **To merge smart objects:**


1. Create smart objects as normal (see [Create smart objects](https://vicon-help.atlassian.net/wiki/spaces/Evoke18/pages/397968505)).
2. In the **Tracking** panel, select the smart objects that will contribute to the merged object, right-click and then click **Merge smart objects**.
  In the **Tracking** panel, the merged smart object is displayed with multiple pattern preview icons.
3. Enter a name for the merged smart object.  
The selected smart objects are replaced with a single composite smart object, retaining the origin of the first selected object.
  In the **Properties** pane for the merged smart object, the properties of the combined objects are displayed (the smart object that was selected last appears first in the Smart Clusters section). Note that in the following example, the Advanced properties > Macro (inline-media-image)

 are displayed.

## Merge additional markers into smart objects

In addition to merging smart objects, you can combine them with additional markers to create more complex objects while maintaining smart object functionality (for example, adjustable patterns). This enables smart objects to benefit from more widely spaced LEDs, enhancing tracking performance and visibility.


    **To merge additional markers into a smart object: **


1. In the **3D View**, select the required smart object and the additional markers (Alt+drag or drag only, if the option ***Alt***** key to select in views** is cleared in **Preferences**).
2. In the **Tracking** panel, right-click on the object and select **Merge Smart Objects**.
  In the 3D View, the merged object is displayed.
  In the **Tracking** panel, the composite object can be identified with a new icon next to the object name.
  You can save this composite object as a template and use it as a family of objects, each with a unique smart object pattern for identification.  
Note that because these additional markers are not controlled by a smart object, they cannot be enabled or disabled with the rest of the composite object.

## Split a merged smart object

If you need to split smart objects that you have previously merged, you can separate them again.


    **To split a merged smart object:**


1. In the **Tracking** panel, select the merged smart object.
2. Right-click the merged object and then click **Split Smart Objects**.  
The separated objects are given the name of their device slot (eg, Top, Front), appended with a number if that name is already in use.
