Exercise – making a procedural tree

In this exercise, we will show you how to make a procedural tree, which includes two items, the leaves and the trunk of the tree. Let’s get started with this exercise!

We will start by creating a line, which we will thicken into the shape of a tree trunk. After that, we will randomize the mesh to create the illusion of tree bark. Then, we will create some Ico Spheres and place them around the tree trunk. To finalize the project, we will merge all these objects into one mesh.

Making the node tree

Let’s start by making the tree trunk; this is the first step we will be taking to make this procedural tree.

Making the tree trunk

The idea of the tree trunk is that we will take a Curve Line node and modify the radius of this Curve Line node using a Spline Parameter node and a Float Curve node to appear like a tree trunk. Then, we will use the Set Position node to add more detail to our tree trunk:
