# Object Groups

Virtual Object groups share the following characteristics:

* Multiple VO groups can be created, and a Virtual Object can belong to more than one group.
* If a Hitbox is added to the VO Group, all members of the VO Group must have a Hitbox with the same name.
* Adding an attribute to the VO Group will create that attribute on all members of the VO Group during experience time with the same initial value. A customizable attribute with the same Attribute Type and name as a VO Group will override the VO Group's attribute value if the VO is a part of the VO Group.<br>
