Before you begin, ensure you have created any necessary smart object templates:

- Smart object templates are provided for Backstrap, Hat, OculusRift, HPReverb, HTCVive, and Pulsar, so you don't need to create these.
- Note that you can merge smart objects (see [Merge smart objects](https://vicon-help.atlassian.net/wiki/spaces/Evoke16/pages/10589070/Work+with+smart+objects#MergeSOs)), which is useful for the head in particular.
- If you are using a backpack, you must create your own template (see [Use smart object templates](https://vicon-help.atlassian.net/wiki/spaces/Evoke16/pages/10589070/Work+with+smart+objects#UseSOTemplates)). When you do this, adjust the object origin offset (see [Change a smart object's origin](https://vicon-help.atlassian.net/wiki/spaces/Evoke16/pages/10589070/Work+with+smart+objects#ChangeSO_Origin)) to match the depth of the backpack, so Evoke knows where the participant's back is in relation to the markers that it tracks on the backpack.

Also ensure you have enabled Evoke to track Pulsars and props by creating the necessary smart objects and basic objects (see [Create smart objects](https://vicon-help.atlassian.net/wiki/spaces/Evoke16/pages/10589070/Work+with+smart+objects#CreateSmartObjects) and [Create basic objects](https://vicon-help.atlassian.net/wiki/spaces/Evoke16/pages/10587193/Work+with+basic+objects#CreateObjects)).

> ✅ **Object tracking only**   
> ✅ If only object tracking is required, you can auto-assign clusters without character solving or retargeting.   
> ✅ To use this option, in the **Processing** panel, ensure the Advanced options are displayed > Macro (inline-media-image)
> ✅ 
> ✅  and in the **Characters From Clusters** section, select ** Disable ****Solving**.

After you have finished these preparations, you can start creating the characters in Evoke (see [Create characters](https://vicon-help.atlassian.net/wiki/spaces/Evoke16/pages/10586369)).
