Modeling low poly rocks

Rocks are really simple to build—especially low-poly ones. We’re going to make two kinds of rocks: a fairly normal boulder and a flatter one.

The process here is a bit different. You’ll start with a mesh, then mess it up and randomize it. You’ll use the Knife tool to add new edges and vertices, and Proportional Editing to shape it.

Let’s start by making a basic rock shape to build upon.

Creating the basic rock shape

Here’s how you model the basic rock shape:

1. Add an icosphere.
2. In the Operator menu, change the subdivisions to 1, for the simplest possible sphere.
3. Press Tab to go into Edit Mode.
4. Switch to Vertex Select mode.
5. Turn on Proportional Editing by pressing O.
6. Now, you need to flatten the bottom of the sphere. Select one of the bottom vertices and move it upward with G to flatten the bottom of the icosphere. (Don’t worry about making this perfect; just aim for mostly...
