Popping a Soap Bubble

Bubbles! We have a bit of a thing for bubbles here at Entagma. But the one classic Houdini setup we have not done yet is a bubble pop. So let’s fix this right now! Download Project File

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 […]

Machine Learning with ONNX in Houdini 20

With Houdini 20 we got our first official machine learning node from SideFX. While we previously had example scene files that did machine learing related stuff or plugins like mlops, this is the first machine learning tool that you get just by installing Houdini. So […]

Sci Fi Panel Deformer with OpenSubDiv Patches

In this episode we’re using a little geometry processing trick to build a sci fi panel deformer, much like some of the tools in the Tissue addon for Blender. We’ll also learn how to use some of the OpenSubDiv functions within Vex in Houdini. Links […]

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 […]

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 […]
