After you have created the characters in Evoke and prepared the participants (see [Create characters](https://vicon-help.atlassian.net/wiki/spaces/Evoke18/pages/397969439) and [Prepare the participants](https://vicon-help.atlassian.net/wiki/spaces/Evoke18/pages/397969461)), you can assign objects and calibrate the character for each participant in these ways:

- **Automated workflow**: For each character, assign one or two reference objects (typically these are the Pulsar clusters for the head or spine) to the correct slots, designating the remaining objects as auto-assignable. The remaining objects are automatically assigned to the correct slots in a single step when you calibrate the character (see [Automatically assign objects and calibrate characters](https://vicon-help.atlassian.net/wiki/spaces/Evoke18/pages/397969552)). For best results, use two reference objects, although this is not essential.
  This is normally the quickest and easiest way to assign objects and calibrate characters.
  :check_mark: **Auto-assign for 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**.
- **Manual workflow**: Manually assign each smart object (or basic object) to the correct slot, and finally, calibrate the character (see [Manually assign objects and calibrate characters](https://vicon-help.atlassian.net/wiki/spaces/Evoke18/pages/397969598)).
