Stable Diffusion 2.0 Quickstart

It’s come so far that even Mo couldn’t ignore AI any longer, so he reluctantly started diving into diffusion models. When he emerged a month later (and very unkempt) this is what he found out. This tutorial covers installing Stable Diffusion 2.0 using Automatic1111’s webUI, […]

Quick Tip: Setting Up A Default Scene In Houdini

Mo is back from berlin where he spent a few days with Colors And The Kids One of the questions tackled there was how to set up a scene file that’d automatically load when Houdini started up. Turns out Houdini looks for a few script […]

KarmaXPU Quickstart Pt.4: Excursion – Visualizing Lipid Membranes

Notes:– I’m recommending to stay away from refractive materials in rendering. This is due to the fact of this particular group of students having limited rendering resources. If however you have those resources, go wild! Mo had the pleasure of joining Dr. Jeroen Claus of […]

KarmaXPU Quickstart Pt.3: Excursion – Visualizing Proteins

Notes:– It *could* be that 1 Houdini unit = 1 angstrom (which is 0.1 nm)– I’m recommending to stay away from refractive materials in rendering. This is due to the fact of this particular group of students having limited rendering resources. If however you have […]

Nerd Rant 2.0 Ep. 22: Manu’s Dad’s Paintings

While moving, Manu unearthed a part of his dad’s portfolio of oil and watercolor paintings. Mo and him discuss his father’s art style, marvel at some contemporary art and ramble on about growing up with a painter.

KarmaXPU Quickstart Pt. 1 – Basic Lighting, Shading & Rendering

In this tutorial we’ll shade, light and render the geometry we created in our previous tutorial, inspired by Alex Valentina’s Work for Form Mag. We’ll be setting up a simple scene graph in solaris, import and light our geometry using an HDRI and then spend […]

KarmaXPU Quickstart Pt. 0 – Creating Our Test Geometry

It’s finally time we talk about Karma again. Nope not your spiritual system, but Houdini 19.5’s built in new’ish rendering engine. It’s been making quite fast progress since the time it’s been released a few versions back, so in our opinion with KarmaXPU being in […]

New In Houdini 19.5 Pt 4: SOP FLIP Fluids

One of the major milestones in Houdini 19.5 is the SOPification of FLIP fluids – allowing for a much more streamlined setup of fluid simulations. In this video Mo goes over the basics of the new workflow, including custom viscosity and density for our liquid. […]

Giving Birth Using Vellum

Sometimes we get the weirdest questions. And we’re quite thrilled about them! This time our friend Patrick (https://www.altshift.de/) approached us with a.. let’s call it special Vellum setup and some questions about how to make all Elements interact properly and animate them. Resulting in whatever […]

Demystifying Sevilla’s Parasols: Waffle Structures

At a recent Houdini meetup, Luc Morroni came up with quite an interesting tutorial topic: Procedural waffle structures, like the ones used in Sevilla’s Metropol Parasol. Seems easy enough at first I thought – but as always, the devil’s in the details. In this case […]

Demystifying Hamburg’s Concert Hall’s Acoustic Panels

Having visited Hamburg recently I was smitten by the city’s concert hall, the Elbphilharmonie. What looks quite minimalistic from afar turns out to be an incredibly detailed building. Of special interes to me were the acoustic panels within the main concert hall, developed by Yasuhisa […]

OFFF Special: My First Vellum Sim

Back from OFFF 2022 and well rested, we managed to upload our talk’s very quick example of how to build and export your very first Vellum cloth simulation in Houdini. Enjoy! Download Project File

Nerd Rant 2.0 – Ep.18: CG vs. Photography

Manu and Mo ramble on about what sets CG and photography apart and what might make them closer than they appear at first glance. Rethinking Photography (German): https://fotografieneudenken.de Chris Hoffmann / Ugly Stupid Honest: http://www.uglystupidhonest.com

Creating An Abstract Wire Sculpture

One of those classic setups again! This time we’re combining custom point advection with a few nifty techniques in Houdini to analyze how our base geometry is shaped and where its edges are. Also we’ll talk briefly about a basic rendering setup in Octane. Napoleon […]

Packing Rigid(ish) Bodies In Vellum

Yes, we covered this in our “packing the Torus” tutorial, however back then we didn’t have Vellum! You draw the conclusions yourself! Seriously though, using vellum for rigid body intersection detection and resolution can be a neat trick when you’re depending on a unified simulation […]

Python in Houdini: Controlling An Embroidery Machine (DST Export)

In what might be our most useless Houdini tutorial to date, Mo covers exporting Houdini geometry for use in an embroidery machine. Yep that’s right. You’re welcome. Setting up Python for Houdini: https://youtu.be/aUdC8p17QEc Virtual Embroidery in Houdini: https://youtu.be/RgLcREpwaU4 Info on the .dst file format: https://edutechwiki.unige.ch/en/Embro… […]

Nerd Rant 2.0 – Ep.13: Learning Houdini With Vincent Schwenk

This is a special nerd rant – just an excuse to upload well over an hour of Vinz and Mo struggling with understanding / teaching Houdini to an absolute beginner. So if you’re thinking of learning Houdini, this call where Mo introduces Vinz to the […]

Houdini Tutorial: Melting Things using FLIP

Learn how to turn any object into molten lava by adapting one of Houdini’s presets to liquify any geometry. Ben Watt’s tutorial that triggered Mo to look into this. While we’re not talking about shading & rendering in here, we provide a scene file that’s […]

Nerd Rant 2.0 – Ep.12: Digital humans

While pondering what makes a decent digitally created human figure, Manu & Mo go almost toe-deep into the philosophical aspects of what believable digital humans would mean technologically and for society. Don’t expect mentions of elk meat, saunas or chimpanzees though.

Simulating A Rubber Band Ball In Vellum

Again Patrick triggered this one by asking if we could have a look at a setup he’s been working on. And boy did we like what we saw. Mo decided to simplify it a bit and slow it down so it could be used to […]

Nerd Rant 2.0 – Ep.10: Working Remotely

Suffering through German autumn part two: Manu & Mo finally got the heaters running and aren’t freezing anymore. Fantasizing about working from some warm and sandy beach, they discuss the pitfalls of and solutions for working remotely.

Smearing Paint using FLIP

We’ve been asked by Patrick how to pull off something like these beautiful paint smears in Houdini, so we got to work. Using basic FLIP techniques will get us quite far, we just have to find the right settings. (Haha. “just” finding the settings…) In […]

Quicktip: New Grouping Behaviour In H19

By a comment on one of our videos on YouTube we stumbled upon a strange behaviour in H19 which took us a few minutes to figure out. Turns out grouping expressions are evaluated slightly differently in Houdini 19. A single short forum post got us […]
