Welcome to this three part tutorial series on how to create a procedural railroad in Houdini for game engines like Unreal and Unity. We'll go over the basic generation of the tracks, some colourcoding and parameters before diving into Unreal for materials and collision!
1 | Basic Parameters & Attributes
In the first lesson of our Railroad series, we'll go over some basic curve-based generation of our railroad. We'll start off with some of the basic attributes and show you how to create some preset in your parameter interface!
2 | Unreal Materials & Parameters
In this lesson, we will continue and create an HDA from the previous setup and generate collisions and add some materials from the existing ones in Unreal.
3 | Introduction
In the third lesson, you will learn how to generate more detail in our balast, by instancing a single box (deformed with the mountain node) to generate a realistic setup in Unreal.
