One of the most exciting features that Houdini 17 introduces is Vellum: A new simulation framework based on XPBD. (Extended Postion Based Dynamics – In essence grains on steroids.) That means stable and fast simulation of (almost) everything softbody: Cloth, Wires and well – softbodies. In this quickstart series we’ll take you through the bare basics of how to get started using Vellum.

Today we’ll create a procedural rope and simulate it using the grain solver. There are always many different ways to achieve stuff in Houdini. In this tutorial I chose the VEX route to generate the rope. This gives a nice self-contained node that can easily be turned into a digital asset. The procedural rope is then deformed to a simulated wire using wire deform.
Here at Entagma we love to deal with yarns. This video extends the “yarn-effects” with a crochet approach. Using the delaunay triangulation of an input mesh and its dual diagram, the voronoi mesh, we build a procedural model that uses point color to blend smoothly between the two. That gives an intricate pattern, especially in the blending regions. As a bonus we animate the effect.
There are many render engines out there nowadays and it’s not easy to choose the right one. CPU or GPU, biased or unbiased. In this video we discuss the pros and cons of different render engines from our humble point of view. As a bonus we talk about LUTs and view transforms.
Although they are technically called “Game Tools” there are quite a few cases in which you might want to use these assets built by the talented folks at SideFX. For example when you’re gonna do geodata visualisation.

This is an experimental post. As we often sit down to discuss different topics from our Entagma life, this time we just switched the camera on and created a vlog-type movie for you. Just the right thing to watch on a otherwise boring “no-new-tutorial Monday”.
After Mo’s post about building his own workstation we started to discuss further what the best strategy is to acquire a machine for GPU rendering. Buying off-the-shelf hardware has advantages, building your own box has advantages too. Here’s 20 mins of Entagma talking about the pros and cons of building your own PC.
It finally happened – here is the long feared hardware episode you’ve not been waiting for! As Mo recently started freelancing, he decided he’d need a new computer. Also he decided to build it himself. Enjoy the resulting chaos.

Last week Germany was still under a massive heat wave. And an office doesn’t get colder by running smoke sims and rendering. That’s why I had to keep this one relatively short (let’s call it a speedrun): We’ll build a particle system advected by a smoke sim and demonstrate how to set up instancing in Redshift.

Niklas Rosenstein is with us again! And if Niklas is in the house, chances for some Python code are pretty high. This time we’ll import vectors from Illustrator into Houdini, create an isocontour-effect and export the result back to illustrator.

Blending smoothly between a high-poly mesh and its low-poly representation is a subtle but useful effect. In this tutorial you’ll learn how to create two versions of the same object, one smooth and one facetted, with the exact same topology. This enables you to blend between the two using a falloff value.
