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 […]

New In Houdini 19.5 Pt 3: Shallow Water Solver (Plus KarmaXPU)
Mo is going to SIGGRAPH – and he’s running late. So this text admittedly is very brief. In this video we’re gonna (ab)use Houdini’s new shallow water solver to create this abstract streamline animation. Download Project File
Pack Points inside Objects with Geometry Nodes
Geometry Nodes offer a node to distribute points on the surface of another object. But scattering points inside of the volume of a object is not as simple. In this tutorial Manuel explains how to build a Geometry Nodes setup that does just that. First […]

Mograph Liquids: Controlling FLIP Fluids Via Curve Forces
Been going through a few of Jeff Wagner’s feature presentations from a the last few Houdini releases and stumbled upon a gem which I thought I’d base a setup on: Controlling FLIP fluids using a curve. Throw in a tiny bit of VDB/VEX magic and […]
New In Houdini 18.5
Full Playlist Here Houdini 18.5 is out! And here are the features that got us excited! Of course there’s much more. (SOP based rigging anyone?!) We had great joy in seeing that Karma has come a long way and that real time pyro sims in […]

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
Quick VDB Clouds
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.
Mandelbrot and Mandelbulb
The Mandelbrot set – the mythical King of fractals. The one that started the whole fractal craze in the 80s and 90s. In this video we’ll implement not only a classic Mandelbrot set that will yield the omnipresent image of that weirdish ridged shape, but […]
Quicktip: Abstract Shapes
After publishing the VDB denting tutorial, we received some questions regarding how we created the geometry used in the preview rendering for that tutorial. In this quicktip we’ll show you how to create the organic shapes we used when testing that setup. It’s a neat […]
Houdini: True 3D Reaction Diffusion
You might have seen this effect more frequently during the last months: Those growing organic blobs that cover a surface in intricate Patterns (sometimes resembling the texture found in a Keith Haring painting). These patterns are the result of a process called Reaction Diffusion.
Houdini: Curl Noise Flow
This short tutorial ist inspired by the amazing work of deskriptiv. Seriously one of the most inspiring artist collectives I’ve come across in the last year. What (in my opinion) is being done here is a curl noise flow around a given surface that is […]
Houdini: Boolean Volume Denting
When I saw this tutorial on Greyscalegorilla, it occurred to me that although I liked the results a lot the process of sculpting and posemorphing would be a bit too unflexible for my needs. And of course it would also be too tedious for a lazy […]
