Rendering Houdini Effects in Eevee

Since the release of Blender 2.8 people are looking into Eevee, their rasterisation real time render engine. Eevee is free and gives good and quick results, so why not bringing over effects from Houdini to render there. In this tutorial I’ll walk you through the […]

Analytical Foam

As position based simulation techniques are very fast theses days, it is possible to use them to confrom intersecting spheres to each other, to model foam. Nevertheless there are other possibilities, too.

Polyfolding – Part 1

This is the first part of a two part tutorial. Part two will be available soon. Polyfolding is an interesting effect where you split up an object to individual bands and make them curl up. It can be used to disintegrate an object or make […]

Implementing A Position Based Cloth Solver From Scratch

Position Based Dynamic effects are quite popular today as these provide us with fast, predictable and stable simulations. Houdini comes with PBDs packaged inside of the “Grains” node and with H17 with XPBD inside of the vellum solver. This video shows how to implement one […]

Adding Houdini To Your Arsenal

Dear Patrons, “Adding Houdini To Your Arsenal” is our next premium course. It addresses 3D artists that are proficient with another 3D tool and want to learn to use Houdini in companion to their main tool or exclusively. The course requires good general 3D knowledge, […]

Create and Simulate a Procedural Rope

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 […]

Crochet – Blending between Delaunay and Voronoi

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 […]

Nerd Rant: Render Engines

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 […]

Nerd Rant: Hardware – DIY vs. Pre Built

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”. […]

Low Poly Transform

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 […]

Kitbash Vein Growth Part 1

This tutorial shows you how to create a procedural vein, that is composed of small segments that you drawn by hand. This way the overall look of the vein is art-directable.

Quicktip: Signed Distance Outlines

S Due to the fact that the SDF is defined in 3D space the setup can easily be animated, too, to create some fake water ripples. Download Project File

Directions From Growth

When dealing with growth solvers, often you not only need the growth itself, but a direction vector. For exapmple to copy feathers onto a surface, or other directed object, like knitting loops. In this tutorial Manuel explains how to calculate direction vectors on the surface […]

TD Essentials: Parallel Transport

Curve framing is important for a lot of things, like trajectories, creating geometry from curves or aligning copied geometry to curves. In this tutorial Manuel implements the parallel transport algorithm that transports an initial normal vector along a curve to create a smoothly varying frame. […]

PBD: Dynamic Weave

Today it’s about dynamically generating a piece of woven fabric. Manuel explains how to write a VEX wrangle in the DOP context to generate connecting yarns in every frame.

Procedural Modeling Of Water Droplets

If you want to make your product appear nice and fresh in your TV commercial, chances are that you’ll put water droplets on it. This effect is very popular in advertising. In todays installment of the Entagma tutorial stream, Manuel shows you how to procedurally […]

Live Rendering of Heightfields in RS

Heightfields are a nice addition to Houdini 16 for environment work. They more or less replicate the functionality of programs like Worldmachine. In today’s tutorial Manuel shows you how to create a terrain from scratch in Houdini and how to render it directly in Redshift3D, […]

Scaling The Bullets Dynamically

Today we scale live dynamic objects and make the scaling affect the running sim. You’ll gain some insights into how the Bullet solver inside of Houdini works and how it operates more efficiently using packed primitives. Manuel goes over the ins and outs of modifying […]

VEX in Houdini: Space Colonization

Branching growth is fascinating as it has a lot of hidden structure to it and is very intricate. Many methods have been proposed over the years to model branching structures, like trees. One algorithm that is particularly beautiful and simple is the “Space Colonization” algorithm, […]
