# Grass

> The detail prototype will use the grass shader.

## Definition

* **Type:** Field
* **Namespace:** [UnityEngine](/engine/6000.0/script-reference/unityengine.md)
* **Assembly:** UnityEngine.TerrainModule

```csharp
Grass = 2
```

### Remarks

When using custom meshes in this mode, control the wave amount by setting vertex color's alpha channel. Grass will take normals from terrain directly underneath it, so that the shading matches the terrain.
