Detailed Course Structure and Lessons

Our journey through ‘Blender Geometry Nodes for Beginners – Procedural Bridge Generator’ consists of nine detailed lessons that introduce essential techniques, one at a time.

Lesson 1 – Introduction

In this first lesson, you’ll get a complete overview of how the Geometry Nodes setup works. We’ll cover the features of the course project, providing a roadmap for the bridge’s design elements, such as customizable shapes, holes, railings, and stone paths.

Lesson 2 – Profile Shape

Create the profile of your bridge. In this lesson, you’ll design the main body and railing supports, using inputs for width, height, and rail parameters. You’ll combine three quadrilateral curves to form the bridge’s base structure, setting up all necessary controls for customization.

Lesson 3 – Bridge Shape

Now, let’s sweep that profile along a curve. You’ll create the bridge’s shape by sweeping the profile curve and adding controls for height displacement and steepness to give the bridge a unique look. Using the offset on the Z-axis and mathematical functions, we’ll make the bridge more visually interesting and realistic.

Lesson 4 – Customizable Holes

Add depth and dimension to your bridge by creating customizable holes. In this lesson, you’ll learn to add holes in the bridge body using cylinder shapes. We’ll set up input parameters for hole count, spacing, center/side scaling, and Z offset, allowing you to tailor the bridge to any scene.

Lesson 5 – UV Unwrapping and Material Application

In this lesson, we’ll dive into UV unwrapping techniques specific to curved and complex shapes. You’ll learn how to unwrap the bridge and apply basic materials, giving it the final touches needed for a professional appearance in your 3D scenes.

Lesson 6 – Introduction to Stone Path Creation

Bring more life to your bridge with a stone path. We’ll introduce the stone path generator, a feature that adds realism and character to your bridge. You’ll learn the basics of setting up stones in a straight line along the bridge, a foundational step before aligning stones to custom curves.

Lesson 7 – Generating Stones

Create a seamless stone path along the bridge’s length. You’ll generate stones along a straight line that matches the bridge’s input curve or mesh length. We’ll focus on separating stones along each input curve for detailed control and dynamic adjustments.

Lesson 8 – Aligning Stones to Curves

In this lesson, we’ll align the generated stones to the bridge curves. You’ll learn techniques to ensure the stones follow the bridge’s shape, making them look naturally placed. This step helps create a cohesive look and ensures the stones blend seamlessly with the bridge structure.

Lesson 9 – Adding Stones to the Bridge

Finally, we’ll integrate the stone paths with the bridge’s geometry. You’ll generate and separate curves from the bridge geometry to create a realistic stone pathway over the bridge. Additional input options will be added to give you full control over stone placement, scale, and alignment.
