3D Trees with Blender Geometry Nodes

Build a tree system you can keep shaping. In this Blender Geometry Nodes course, you will work through procedural branches, roots, mesh generation and leaf placement, then add movement with falling-leaf simulations. The aim is to understand how the tree is constructed so you can adjust its form rather than model every branch separately.

Vlad from 3D Tudor guides you through the generator in stages. You begin with the branch system, develop the tree's structure and surface, and then tackle foliage and particles. Each stage adds a useful part to the same procedural workflow.

Build the trunk and branching system

Start with an overview of the tree generator and the branch-generation workflow. Work with split ends, curves and repeat zones to develop branching structures, then introduce controls and variation that change the tree's overall shape. The lessons progress from branch-system basics to more advanced branching and internal data.

This gives you a way to explore different silhouettes through the node setup. You can investigate branch density, length and variation while keeping the parts connected in a procedural system.

Add roots, surface variation and bark materials

Extend the tree below the trunk with a root system. Use displacement and procedural variation to break up overly regular forms, then move from curves to a mesh that can receive materials. The mesh-generation and UV-mapping lessons connect the structure of the tree to its textured appearance.

You will work through UV refinement for the bark rather than leaving the generator as an untextured shape. The supplied resource pack includes bark and foliage materials and a finished project file to support the lessons.

Control where the leaves grow

A convincing tree depends on more than its trunk. The leaf-distribution lessons cover the basics of placing foliage and then develop more advanced placement methods. You will explore how the position and density of the leaves affect the canopy and the character of the finished tree.

Use the material and leaf variations supplied with the course to explore different appearances. The project is a practical setting for learning how branching, surface detail and foliage distribution work together.

Make falling leaves part of the scene

The final technical section introduces a basic particle system and develops it into more advanced particle simulations. You will use Geometry Nodes simulation workflows to create falling leaves, adding a moving element to the tree project.

Who is this course for?

This course suits Blender learners interested in procedural nature, environment artists who want more control over their trees, and artists who prefer building an adjustable system to repeating manual modelling steps. Familiarity with Blender navigation will help you concentrate on the node lessons. You do not need an existing tree generator to begin.

What will you take away?

You will have worked through a connected tree-generation workflow: branches and roots, mesh and bark UVs, leaf placement and falling-leaf particles. More importantly, you will have seen how each part contributes to a tree that can be adjusted and explored through its node setup.

Use the introductory preview to look at the generator and the teaching approach, then follow the course in sequence as you build up the system in Blender.
