# Terrain Data Manager

The **Terrain Data Manager** component is a utility for handling terrain interactions when using **Easy Grid Builder Pro** with terrains.

This component is located in <mark style="color:purple;">**SoulGames > Utilities > Scripts**</mark> and is included by default as part of the **Utility Managers** child GameObject in the **Grid Managers Prefab**. If your project doesn’t use terrains, you can safely remove this component.

## <mark style="color:green;">Example Use case</mark>

When Buildable Objects modify the terrain in runtime (e.g., flattening), these changes usually persist after exiting Play Mode. The **Terrain Data Manager** saves the original terrain data when entering Play Mode and restores it upon exiting, ensuring the terrain resets to its initial state.
