NavMeshModifier

NavMesh Modifiers adjust how a specific GameObject behaves during NavMesh baking at runtime.

To use the NavMesh Modifier component, navigate to GameObject > AI > NavMesh Modifier.

In the image below, the platform in the bottom right has a modifier attached to it that sets its Area Type to Lava.

The NavMesh Modifier affects GameObjects hierarchically, meaning the GameObject that the component is attached to as well as all its children are affected. Additionally, if another NavMesh Modifier is found further down the transform hierarchy, the new NavMesh Modifier overrides the one further up the hierarchy.

The NavMesh Modifier also affects the NavMesh generation process, meaning the NavMesh has to be updated to reflect any changes to NavMesh Modifiers.

Note: This component is a replacement for the legacy setting which could be enabled from the Navigation window Objects tab as well as the static flags dropdown on the GameObject. This component is available for baking at runtime, whereas the static flags are available in the editor only.
