We’re overwhelmed by this season and the feedback we receive from you – thanks a lot for your support and the frequent input you share! As you might be aware we’re running Entagma in our spare time, which sometimes makes it difficult to stick to our ambitious weekly release schedule. Read More
Knitting in 3D is quite popular these days. Although it is not too hard to achieve, building a knitting setup presents some challenges to the TD. In this tutorial Manuel shows you one way of modeling a knitted 3D object and a method of making the knit conform to the animated mesh.

Quite some time ago I was trying to cook up something like the guys at moviebarcode.com: Some setups that’d deconstruct a given movie into its individual colors in a visually pleasing manner. Recently I thought it was time to try another attempt. Instead of linearly mapping the individual frames’ colors on a 2D plane, this time I wanted to create something that took advantage of 3D space.

When we saw Andy Lomas’ “Aggregation” series a few years back we were struck. How could you generate those intricate particle sculptures? The series’ title hinted at one possible solution: Diffusion limited aggregation or DLA. In this tutorial we’ll build a basic DLA setup using VEX and volumes. Also we’ll talk a bit about rendering our result in Mantra and Redshift.

At FMX 2017 Entagma had the pleasure to talk as part of “Houdini Day”. Among other things we explained how to create a propagation growth solver. Here we’ll show how to build this setup. We introduce the concept behind propagation growth and implement the solver in VEX. It is point based although one might want to implement it directly in volumes. The point approach is simpler to tackle, though.
By far the most frequent question we received after our minimal surfaces tutorial was “how do you build that bubble shader?”. The wait is over – in this tutorial we’ll go over how to build a plausible soap film shader in Houdini’s Mantra and Octane standalone.

This episode we managed to get away from our workstations and head outside to Munich’s beautiful olympic park. There we found some prime examples of the shapes soap films form when they evolve between metal wires.

Dense packings of objects onto surfaces always look stunning. There are many analytical algorithms out there to compute such a packing. In this video we’ll explore a simulation based approach to achieve a dense packing of particles with varying radius. This is more versatile and easily allows for a nice packing animation.

We’re happy to present to you another special guest on Entagma – this time it’s Yader (who some of you might know through his great Cinema 4D tutorials). In his tutorial he’s gonna shed some light on how he built his Poly Garden setup that allows you to grow abstract polygonal shapes.

When testing out a new render engine (or any tool that can do rendering), one of the typical objects I try to get a decent image of is a quartz crystal. In order to get that right, a rendering needs to contain effects such as dispersion, proper refractions and SSS. In this tutorial I’ll walk you through my first attempt to render a Quartz in Mantra in H16.

Last time I announced a second part to the ripple solver tutorial. And here it is! This time, I rebuild the ripple solver setup by using a SOP solver to update the simulated geometry. Then I show you how to vary the wavespeed spatially. And finally I create an enclosed polygonal body from the simulated grid to be able to use a absorption shader on it.
