Houdini In Returnal

Returnal is built out of separate rooms and each time the player starts a cycle, the rooms are randomly connected. This required us to make a lot of varied rooms. So we decided to heavily automate the art content creation process. In this talk we will go through our Houdini pipeline and see how we built the worlds in Returnal.

From L-System to Humankind Game

Humankind depicts a world made of hexagons filled with millions of various small objects. I will show you how we where able to simultaneously feedback gameplay informations while producing a beautiful and very varied world. Our method resembles an exploration of a decision tree where the nodes only belong to a few categories. It has some similarity to L-System but goes beyond by adding sensitivity to values ​​collected from the environment. We will using actual samples of problem that we had to deal with, from simple to more complex situations.

Why the procedural approach could fail

When I wrote procedural tools for small projects and myself, I thought I was good at this. Then I started to write tools in the studio with more than 100 artists and I realized I’m making mistakes in very unexpected areas. This is the story about those failures and how tech artists can avoid them.

You might have heard about this not so recent thing called AI. The past months have been a whirlwind of releases, shitstorms and new means of creating artworks. In this two part talk, Paul Ambrosiussen and Moritz Moritz try making sense of it all by diving head first into the why and how to add this set of tools to your pipeline by duct taping it to our most beloved 3D App, Houdini. Expect a mix of theory, scripting, a good part design and occasional cursing.

Wednesday 19-04-2023 & Thursday 20-04-2023

All masterclasses will be on-site and run over the course of two days (Wednesday and Thursday) from 9:00 to 17:00. To participate you need to bring your own laptop or hardware. Tickets include drinks, lunch and a conference ticket for Friday April 21.


The key concept driving the level generation behind Unexplored and Unexplored 2 is model transformation. This concept taken from model driven engineering suggests that the generation process is broken down into multiple, self-contained steps. The output of each step is a ‘model’ of the level you want to generate. The first model might contain the general outline, while another model might represent basic physical space, while a third represents the structural relations between gameplay elements.

During this two-day workshop we’ll use Ludomotion’s in-house generation tool Ludoscope to explore the notion of model transformation. We will be breaking down the generation process in multiple steps, experimenting with different types of models and transformations, and trying out several generative / transformative grammar techniques to make it all work. For the workshop Ludoscope will be made available, but you can also bring your own generation tools and techniques.

This Masterclass consists of two sessions.

Houdini Fundamentals
LThis workshop will introduce artists to Houdini, and give them a sound understanding to continue their studies. We will make our first procedural model by building a solar system generator with a cool user interface. We will toon shade it so we can render it in no time. Next we will learn all about Houdini’s secret power: attributes. We will then take this knowledge and use Houdini’s CHOPs (channel operators) and RBD (rigid body) systems to procedurally animate some “Freaky Balls” dancing to the music of your choice! Finally we will light and render our scene, so you can export the movie to your social media platform of choice!

Attendees should have some familiarity with 3D software like Blender, Maya, 3D Studio Max, etc.

KineFX: Animating Environments and Props
Since KineFX was released, there have been plenty of great resources put out about using it for various character related workflows, like retargeting, procedural animation, ragdoll etc. In this workshop, we will not be talking about any of that. Instead, we will get to explore a less popular, but equally fun and rewarding area where KineFX can be of great help: environment and prop animation. Join us for a beginner/intermediate session where you will get to build something fun and hopefully learn a new thing or two.

Finding Patterns – The Math Behind HEXAGONA
Who likes patterns, is all about procedural systems, loves world-building, and has a not-so-secret obsession with hexagons? I know I do, and that’s what has led me to build HEXAGONA in the first place. If you do too, we’re friends already and you should also come to my workshop where I will be breaking down this project. HEXAGONA is a hexagon-tiled procedural board generator, developed in Houdini, which can be used in different game engines. For this workshop, I will be presenting my approach to developing it, breaking problems into smaller ones, math and geometrical puzzles, and the beauty of finding patterns. All that while actually building a lite version of it with the core mechanics and key features.

Houdini Data Pipeline Integration
Digital Content Creation pipelines are complex setups which consist of various workflows and software. Some use Unreal Engine or Marmoset to render, Substance Painter and Designer to shade objects, and Houdini with Blender to create procedural or destructive geometry. Houdini is the perfect centerpiece to orchestrate all of these moving pieces and their respective data. In this session we will look at what it takes to build a Python plugin for Houdini to speed up workflows between these common workflows.
