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.

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.

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.

After being asked how to create clouds for rendering in Octane (or any other Engine that supports VDBs) we dove into that topic a bit and the quickest way we found was to use the cloud tools that Houdini provides.

Naive Path Finding

This one is a rather brute force approach for a problem we had to solve on a recent job: Finding a path through a bunch of obstacles. Admittedly what we implement here isn’t a very sophisticated algorithm, but its power lies in its simplicity: It will find a path as long as it’s got enough points available.
