Getting Started with Terrain Tools in Unity Part 1: Interface and Mesh Sculpting

If you love open world games and have ever wanted to make beautiful outdoor 3D environments, this article is for you. Creating a detailed environment has never been faster or easier than now with Unity’s Terrain Tools.

Setup

Start by creating a new 3D project. You don’t need to have any particular pipeline running, but I am using the HDRP for this article. Navigate to your Project Settings>Package Manager, and make sure Enable Preview Packages is turned on.

Open your Package Manager and search for Terrain Tools. Press the Install button.

A pop-up should generate with a link button to Download Asset Samples from Asset Store. Press it.

The link will take you to the asset on the asset store. You can alternatively just go to the asset store and look for the Terrain Sample Asset Pack. Push the Add to My Assets button.
