How to use this asset
---------------------
Firstly, you should run the Demo Scene provided to get an idea of the overall functionality.
Later, you should read the documentation and experiment with the tool.

Hint: to use the asset, drag the TerrainGridSystem prefab from Resources/Prefabs folder to your scene and assign your terrain to it.


Demo Scene
----------
There's one demo scene, located in "Demos" folder. Just go there from Unity, open "Demo1" scene and run it.


Documentation/API reference
---------------------------
Please check the Documentation folder. It contains instructions on how to use the prefab and the API so you can control it from your code.


Support
-------
Please read the documentation and browse/play with the demo scene and sample source code included before contacting us for support :-)

Future updates
--------------

All our assets follow an incremental development process by which a few beta releases are published on our support forum (kronnect.com).
We encourage you to signup and engage our forum. The forum is the primary support and feature discussions medium.

Of course, all updates of Terrain Grid System will be eventually available on the Asset Store.
