Guest Tutorial: Dart Throwing
We’re thrilled to have Andreas Catucci as a guest! Somehow aside from creating amazing work, he managed to record a video on a technique very dear to our hearts: Dart throwing. Sounds like simulating aerodynamics? Not quite. It’s a method to densely pack a surface […]
Interference Patterns On Surfaces
Today we’re revisiting an old setup of ours: Creating intricate interference patterns using circular waves. Time has passed since Mo built the first version of this in 2018 and now, with Houdini 19.5, we got a new node that finally allows us to calculate those […]
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 […]
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 […]
Building a Latent Space in Houdini: Part 1 – Theory
This week we want to give you a lot more insight into what a latent space actually is and how it gets created. In this case not by using Stable Diffusion, but by building and training our own neural net inside Houdini, who’s only job […]
Strange Forests: Creating 2.5D Images with MLOPs and Faking DOF in Pointclouds
Now that MLOPs is released and available for everyone, let’s create some motion graphics using those new tools and combine them with other workflows we already know from Houdini. In this video Chris shows you how he created these strange forest renders while beta-testing MLOPs […]
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 […]
DIY Rendering Engine Like It’s 1975
What do you do when you need fast info passes rendered out but are too stupid to set up something in ROPs and too lazy to use Solaris? Right – you build yourself a 1970s render engine straight in SOPs. Clever? Not sure. Useful? Definitely. […]

Creating an AI Chimera Using Stable Diffusion
We continues poking into stable diffusion by giving a brief overview of what tokens and embeddings are and how the can be manipulated to blend between prompts. Finally we create some nonsensical animals. Huge thanks to Chris Hoffmann (ugly stupid honest) Notebook: Stable Diffusion Deep […]

Stable Diffusion 2.0 Quickstart
It’s come so far that even Mo couldn’t ignore AI any longer, so he reluctantly started diving into diffusion models. When he emerged a month later (and very unkempt) this is what he found out. This tutorial covers installing Stable Diffusion 2.0 using Automatic1111’s webUI, […]

KarmaXPU Quickstart Pt.4: Excursion – Visualizing Lipid Membranes

KarmaXPU Quickstart Pt.3: Excursion – Visualizing Proteins
Notes:– It *could* be that 1 Houdini unit = 1 angstrom (which is 0.1 nm)– I’m recommending to stay away from refractive materials in rendering. This is due to the fact of this particular group of students having limited rendering resources. If however you have […]

Better Texture Tiling
Even if you have a perfect tilable texture with seamless borders you often run into problems when tiling the same texture often to cover large areas. If your texture happens to be irregular you might want to give this tiling trick a try to make […]
Procedurally Create Detroit Agate with a Karma Shader
If layers over layers of car paint accumulate in the factory over the years they create grey rocks with magic hidden inside. Once you start to cut and polish these rocks all the individual color layers are revealed and create a color explosion. In this […]
