Exercise – creating a grassy field
In this exercise, you will be creating a grassy field using the nodes you learned in this chapter. We will start by distributing points onto a terrain mesh, then we will make and instance blades of grass, and then we will give these blades of grass some randomization.
Sketching the idea
In this section, we will think about what steps we need to complete to achieve the goal of creating a grassy field. We will need to model a basic terrain mesh and distribute some points on it; we will also need to model a single blade of grass to use as an instance object. After that, we will randomize the rotation of each blade of grass. To finalize this project, we will also show you how to link materials to your procedural mesh.
The nodes we will need
In this section, we will talk about the nodes we will need to create a grassy field.

It’s a good practice...
