Advanced Setups 29: Python State Sculptures

It’s time for another niche, but sometimes very handy technique in Houdini: Creating Python States and scripting your own viewport handles for your Digital Assets. While this is usually technical director territory, today we’re all about exploring art and design based on this technique, by cr...

Advanced Setups – pt.28: PyTorch Series 2b – Battle of the Latent Spaces

Chris has been busy with PyTorch again! In part 2b we will learn how to create 3d maps of our latent spaces, even if those spaces themselves have a couple hundred dimensions. We will also compare the latent space of our own custom net to OpenAI’s Clip model as well as some good old fashioned al...

Advanced Setups – pt.27: PyTorch Series 2a – Upgrading the Autoencoder

Chris has been busy with PyTorch again! In the next two videos we will continue where we left off with our MNIST autoencoder in the last Advanced Setups video. In part 2a we will upgrade our autoencoder to process larger color images and feed it two custom datasets – One that works pretty well ...

AHTYA 2.0 – pt. 22: Swirly Rocks Projects Part 3

In this episode we’ll finally finish our Swirly Rocks project. This time we’ll build all forces necessary for our cyclones: Forces that pull each piece towards and up those cyclones, as well as swirling forces surrounding them. As in the last video each force will be custom built using the ve...

AHTYA 2.0 – pt. 21: Understanding Vectors Part 2

It’s time we finish our section on vector math! We’ll cover the cross and dot product as well as measuring vector length and a simple way to rotate vectors. And of course each vector operation will get it’s own mini-setup in Houdini.

We’re back at our Swirly Rocks project! Last episode we got an intro into vector math in Houdini and in this one we’ll use our knowledge to build custom forces for our simulation: We’ll get A little overview over how physics solvers deal with forces first and then build our own gravity and ...

AHTYA 2.0 – pt. 19: Understanding Vectors Part 1

Today’s the day we finally bring vector math into our Houdini setups. And this is actually a lot less daunting and complicated as it sounds – for the most part this will honestly feel more like a puzzle game than high school math. So in this video we’ll learn why you should care about vecto...

AHTYA 2.0 – pt. 18: Swirly Rocks Project Part 1

We’re starting our next big section in AHTYA 2.0! Over the next five videos, we will build the swirly rocks setup from the teaser and learn, how we can use vectors to art direct the forces driving our rocks simulation. Part one is all about the prep work for our project: We’ll learn about Hou...

KineFX 101 – pt. 31: Fixing Faulty FBX Files

KineFX doesn't always like the FBX files you load in and this turned out to be by far the most common problem you guys had, while following the course. So in this video we're showing how to identify a problematic file and a number of different ways to fix it.

AHTYA 2.0 – pt. 17: Dataviz Mini Project

In this video we're building a setup that's almost a rite of passage for every new Houdini user: Taking what's essentially a spreadsheet and turning it into a beautiful visualization - all through the power of attributes and vops.

AHTYA 2.0 – pt. 16: Understanding VOPs in Houdini

We're continuing our work on attributes and take a look at a node that allows you to build really granular and custom systems for modifying attributes: It's time to look at VOPs (and also taking a tiny glance at VEX as well)!

AHTYA 2.0 – pt. 15: City Model Mini Project

After our little detour covering for loops, it's time to get back to attributes. Until now we used attribs just to add variations to our setups. In the next set of videos we want to get a lot more thoughtful about how we create and tweak attributes to suit our needs - In this case by building a t...

AHTYA 2.0 – pt. 14: Intricate Torus Project

Last video we learned a lot about For Loops in Houdini. This video it’s finally time to put this theory into practice by using them to build a very intricate torus!

AHTYA 2.0 – pt. 13: Understanding For Loops in Houdini

We’re back with a new section of our AHTYA beginner series. This time we’re talking about a somewhat odd but sometimes necessary part of Houdini: For Loops! When do you need them? How do you use them? And why do you find such mixed feelings about them online? We’ll answer all those question...

AHTYA 2.0 – pt. 12: Rendering B: Octane Walkthrough

Octane? Redshift? Karma? Mantra? Solaris? Blender? – When it comes to rendering, Houdini has quite a lot of options for us to choose from. So in the next two videos we’ll look at what method of rendering is best used for which situation and how to prepare your scene for all of them. We’ll a...

AHTYA 2.0 – pt. 11: Rendering A: Overview and Preperations

AHTYA 2.0 – pt. 10: Flower Tube Project Part 2

We’re finally back at our main project of this section! In this video we’ll use our newly gained knowledge of attributes to add lots of little variations to the setup we built last time, making it look a lot more natural and interesting.

AHTYA 2.0 – pt. 09: Understanding Points, Verts, Prims, Details and Edges

In the last two videos we only took a glance at the different types of geometry we can put attribs and groups on. In this video, we’ll answer all questions you might have about them, like: What’s the difference between points and vertices? Why are faces called primitives? Where are my edges? ...

AHTYA 2.0 – pt. 08: Understanding Attributes in Houdini

In the last video we took a deep dive into working with groups in Houdini. In this episode we’ll do the same with attributes – the (arguably) most important concept in Houdini. We’ll take a look at the differences and similarities of attribs and groups, why attributes are pretty much everyw...

AHTYA 2.0 – pt. 07: Understanding Groups in Houdini

In this video we'll explore the first of two very important topics in Houdini, which are Groups. We will take a look at different use cases for groups as well as all the nitty gritty details you need to make use of and manipulate groups in pretty much any setup imaginable.
