# Network state change materials
You can use a network state to synchronize changes to one or more objects' materials.
Component overview
In the `NetworkStateTrigger_ChangeMaterials` component, you can set both a list of materials and a list of Mesh Renderers. You can then call methods to apply a material from the list to all referenced Mesh Renderers.

The following diagram shows an example of how to arrange the components in Unity, and the required references.
