In this short video I explained how to create orient attribute from scratch, to add proper rotation to particles.
Hey ya’ll, here’s a tutorial vid for one of my examples on L-tree madness. Hope you find it somewhat helpful! VEX code: http://tao-universe.uk/snippets/houdini_l_system_vex.txt Original video: https://youtu.be/wKATAFy6IGc

A quick and easy trick to find Points on your geometry by only using VEX in a wrangle node. I show you a simple setups to use a point cloud to find specific points on your geometry.
In this houdiniPill i’m going to take a look into the sample functions. These are great tools for controlling vector randomization. I hope you enjoy it! Sorry for the delay releasing this one. I’ve been quite busy with studio work…

This lesson takes a simple practical example to cover a few more Vex functions. Primarily the video covers how to create a look at using Vex and control objects using distance or height. Download file https://www.dropbox.com/s/tk862d4l0p3czq0/flower%20bloom.hip?dl=0 regards Rohan
In this first houdini pill we are going to create a very simple solver that will make spheres grow until they hit each other. It’s an easy tutorial but some vex and basic houdini knowledge is required. I hope you like it, more coming soon!
Hello everyone, This video is an introduction to Vex, which is the programming language available in Houdini. The video doesn’t require any previous knowledge of programming. Jump to the 4 min mark if you want to directly start with the project and skip the explanation. The video will cover relatively wide range of topics including, […]
A free, two parts, 90 minutes tutorial about how to build a realistic Sun in Houdini software. It covers topics like : vex coding, vector calculus, VDB volumes, particle simulation , magnetic fields and much more. I hope you’ll enjoy watching this as much as i enjoyed doing it. Thank You Bogdan Lazar VFX Artist
This tutorial will cover how to create random motion on a point cloud for shots like flocking birds or planes using only VEX code on a single node in SideFX Houdini. Updated Code (03/09/2017): Here is the final VEX code. I tweaked a couple of things so that there are now UI controls created for […]
Hello guys, I’ve been asked about how to achieve this liquid effect that I shared some months ago so I decided to make a tutorial, sorry for the breath noise on the mic.

An Attribute VOP can run a VOP network to modify geometry attributes, while a Point Wrangle runs VEX and can also modify point attributes that include position. So what is the difference? When would you use one over the other?Houdini VFX Artist Tighe Rzankowski, covers wrangles and attribute VOPs, discussing what their core differences are. […]

In this tutorial I show how to generate lines that follow a surface towards a targetpoint with VEX.

So here is my first tutorial. Hope it’s understandable! About the the rendering: I used Redshift for this, an AMAZING Gpu renderer that rendered this scene with GI in less than on hour on my GTX 980. Also I just put some motion trails in there to make it more interesting (not shown in the […]
