Add detail objects the same way that you would normally through the Terrain component. Nature Renderer will automatically load and render the detail objects from your terrain data.
- Go to the 'Paint Details' tab in your Terrain component.
- Click 'Edit Details...' and choose 'Add Detail Mesh' (recommended) or 'Add Grass Texture'.
- Pick a prefab for the detail and edit the detail's properties.
Detail prefabs require a Mesh Renderer and Mesh Filter component on the root Game Object and cannot have non-assigned materials.
