# NavMesh Setup

Building NavMesh is a must-have step to enable subsequent tasks, such as **Camera Placement** and **Camera Calibration**. More details can be found in the [Navigation Mesh](https://docs.omniverse.nvidia.com/extensions/latest/ext_navigation-mesh.html).

## NavMesh Volume Creation

Check if there is a **NavMeshVolume** in your asset scene to cover the navigable area.

* If there is a **NavMeshVolume**, you can jump to the [Bake NavMesh](#navmesh-baking) section.

* If there is no **NavMeshVolume**, go to **Stage** > **Right Click** > **Create** > **Navigation** > **NavMesh Include Volume**.

  Set the **NavMeshVolume** to cover the navigable area.

> **Note**
>
> It is recommended to set the height of **NavMeshVolume** taller than agents (e.g., characters and humanoids) in your scene, but lower than the ceiling.

## NavMesh Baking

Open the **NavMesh** extension by going to **Window** > **Navigation** > **NavMesh**.

The **NavMesh** panel is shown below.

Go to **Bake Settings** and check whether the parameters are within a reasonable range for your scene.

> **Note**

> The default settings are as follows: **Agent Height**: 180, **Agent Radius**: 25, **Agent Max Step Height**: 1, and **Agent Max Floor Slope**: 1.

Click **Bake** to build the NavMesh.
