Studying Unity’s New Terrain Tools

The upcoming 2018.3 version will bring new tools and improved performance by taking better advantage of the GPU. The new version will also add per-pixel normals for terrains instead of the old per-vertex system for higher fidelity with the same triangle count. You will also get scriptable GPU tools that will help you create your own terrain tools. 

The team has also improved multi-terrain editing giving the ability to paint seamlessly between terrains and manage the connection between adjacent terrains automatically.

What is more, there are now two new terrain assets. TerrainLayer is said to define materials independently of the terrain object (can be tracked across multiple areas), while a new Brush asset is said to define the brush shapes used to paint and sculpt using the terrain tools.
