VEX101 - A (Not So) Quick Recap & Fake Hanging Wires

We decided to record (sort of) a repetition, going over some of the fundamentals in VEX.

Along the way we'll talk about how to generate catenaries: The curves that wires / chains form when ha...

VEX101 - Starting A Function Library

You asked for it (and some of you also already answered it): How do you save your custom functions into an external file, so you can build your own library of functions?

This Quicktip goes ov...

Render Setup: Kitbash Vein Growth

Here's the render setup for the Kitbash Vein Growth tutorial. As always it uses Redshift3D and the "Old Industrial Hall" .exr that you can download from sIBL 2018-06-08 20:37:47 +0000 UTC View Post

AHTYA04 - Working With Clones Part 1

3D packages other than Houdini often offer a dedicated system to control and animate lots of clones. Be it Mash in Maya, MoGraph in Cinema4D or Animation Nodes in Blender. In Houdini you have to bu...

VEX101 - Custom Functions

Functions. We've been using them quite a lot in VEX. Basically every time you call something like rand() or nearpoint() we are using a function. That means calling a separate piece of code that Sid...

AHTYA03 - Noisy VOPs

Hi there,

here's the next AHTYA episode. Besides a plethora of inbuilt compiled operators Houdini offers the possibility to develop your own operators, using the VEX programming language. As ...

As always in UHD glory :)

Render Setup: Rigid Body Constraint Networks

As usual set up to render using Redshift. For texturing we used one of Cornelius Dämmrich's great free textures. Get them here: https://...

AHTYA Schedule

As you might have noticed, the release frequency of our AHTYA premium course stalled a bit lately. This was mainly due to the fact that both of us were/are involved in quite major projects at work. Go...

VEX101 - If-Statements

The last basic control structure we'll be discussing is ubiquitous when writing code: it is the if-statement.

In this tutorial we'll use it to improve our simple point connector setup to take...

Render Setup: Directions From Growth

Here's the render setup for this scene, using Redshift3D. The file relies on the Old Industrial Hall HDR from: http://www.hdrla...

VEX101 - Arrays & Foreach-Loops

You'll need them when building lists, saving connectivity information on your mesh or when looking up nearby points: Arrays.

In theory nothing more than a list of values, arrays are handy for...

VEX101 - For Loops

Suppose you want to calculate a point's position over and over again - but writing down hundreds and hundreds of lines of the same code? Seems a bit tedious. Fear not - the mighty for-loop is your ...

VEX101 - Creating Chladni Patterns

To demonstrate what you can achieve with even basic programming, we set out to create what some credit with starting modern acoustics: Chladni Patterns. Those lines of sand visualize how an oscilla...

Render Setup: Interference Patterns In VEX

Set up to render using Redshift. We used the trusty Barcelona Rooftops HDR for lighting. You'll need to download it from: h...

VEX101 - Generating Curl Noise

Ah! What can be more relaxing than having our copies transformed by everyone's favorite noise - the curl noise? This is the same technique we used to create this course's preview image.

After...

VEX101 - Accessing Other Stream's Attributes

Up until now we've only been accessing attributes on our main geometry stream. But what if we'd like to read another geometry stream's attributes?

AHTYA02 - About Geometry And Attributes

Dear Patrons,

here's part two of "Adding Houdini To Your Arsenal". In this episode I explain Houdinis geometry format in quite some detail. The relationship between points, primitives and ver...

VEX101 - Generating Randomness

Generating seemingly random numbers is a surprisingly elemental and often used part in our VEX setups. In this video we'll talk about the basics of generating random numbers and using them to orien...

AHTYA01 - Intro To The UI And Basic Concepts

Dear Patrons,

so today the Houdini introduction for 3D artists starts, with a basic episode outlining the functions of the different parts of the UI and some of the important concepts of Houd...

Adding Houdini To Your Arsenal

Dear Patrons,

"Adding Houdini To Your Arsenal" is our next premium course. It addresses 3D artists that are proficient with another 3D tool and want to learn to use Houdini in companion to th...

VEX 101 - Functions

Functions are the commands we call in VEX to tell Houdini to do stuff: Create a point, find points nearby, generate random numbers etc.

We go over the general structure of a function call, ho...

VEX 101 - Variables

Another fundamendal building block of our VEX scripts are variables. In this tutorial we go over the theory behind variables and quickly discuss some basic examples of how to use them inside of a w...

VEX 101 - Data Types & Accessing Attributes

EDIT: Aaand of course i forgot to attach the list of Houdini's built in attributes. Here it is.

We'll go over the basic data types we will be using when building VEX based setups. 

VEX 101 - SOP Wrangle Basics

An Attribute Wrangle can behave very differently depending on how you set it up. This is one of the distinctive features of VEX which will be very useful when creating code-based setups.
