VolumeStyleTransfer

Volume Style Transfer With ONNX

In an earlier episode we took a first look at the new ONNX inference node, a node that allows us to use trained neural nets inside Houdini. And today we want to use this node for something usefull – Volume Style Transfer! We want to […]

Melting Complex Objects

Melting Complex Objects Part 2 – Rendering

Welcome to the second and final part of our mini series on how to melt complex objects with fine details, textures and multiple materials. All without melting your pc as well! In the first part we built a setup to retain geometric detail and now […]

Melting Complex Objects

Melting Complex Objects Part 1

You guys seem to like melting things! So over the next two free tutorials, we’re going to answer one of the more common questions: How to melt more complex objects with fine details, textures and multiple materials. All without melting your pc as well! Watch […]

Differential Line Growth

Blender Guest Tutorial: Differential Line Growth

We are happy to bring you another Blender tutorial with the help of Louis Brodnig. He will show you how to create a differential line growth setup with Blender Geometry Nodes that he used in his short film about Emergence. Check out Louis work on […]

Freetut Particle Life

Particle Life in Houdini POPs

Particle Life is a new(ish), super popular autonomous agent system that is able to produce very organic, microorganism-like patterns with particles. So of course we had to build our own version in Houdini, right? In this video we’ll cover the basic ideas of Particle Life […]

Vellum Folding

Paper Folding with Vellum

In this video Chris covers a simple way of simulating origami like patterns in Houdini and Vellum, just using edge groups and (depending on how you count them) three or six lines of vex. We can very much recommend watching Junichiro Horikawa’s previous explorations on […]

Vellum Belt Adjuster

Simulating a Belt Adjuster in Vellum

There are some setups that start out looking quite easy and then get harder the more you start thinking about them. And this belt adjuster is one of them because we got quite a few elements interacting with each other. As usual with Vellum, the […]

Curling Ribbons

Simulating Curling Ribbons in Vellum

The idea for this video came from a question on our Patreon Community Hub, asking us how we’d go about creating curling ribbons in vellum, similar to a very beautiful setup by Playback Design. And, as it turns out, this is a quite fun and […]

Geometry Nodes Simulation: Relax Points

Often you’ll need point distributions with non-overlapping points. Be it that you want to pack scales onto the surface of a fish or distribute vegetation on your procedural terrain. Although the “distribute points on faces” node comes with a poisson disc mode to remove overlapping […]

New In Houdini 19.5 Pt 4: SOP FLIP Fluids

One of the major milestones in Houdini 19.5 is the SOPification of FLIP fluids – allowing for a much more streamlined setup of fluid simulations. In this video Mo goes over the basics of the new workflow, including custom viscosity and density for our liquid. […]

Giving Birth Using Vellum

Sometimes we get the weirdest questions. And we’re quite thrilled about them! This time our friend Patrick (https://www.altshift.de/) approached us with a.. let’s call it special Vellum setup and some questions about how to make all Elements interact properly and animate them. Resulting in whatever […]

OFFF Special: My First Vellum Sim

Back from OFFF 2022 and well rested, we managed to upload our talk’s very quick example of how to build and export your very first Vellum cloth simulation in Houdini. Enjoy! Download Project File

Creating An Abstract Wire Sculpture

One of those classic setups again! This time we’re combining custom point advection with a few nifty techniques in Houdini to analyze how our base geometry is shaped and where its edges are. Also we’ll talk briefly about a basic rendering setup in Octane. Napoleon […]

Packing Rigid(ish) Bodies In Vellum

Yes, we covered this in our “packing the Torus” tutorial, however back then we didn’t have Vellum! You draw the conclusions yourself! Seriously though, using vellum for rigid body intersection detection and resolution can be a neat trick when you’re depending on a unified simulation […]
