Evaluating the Laser Scan Effect in Solaris, Redshift and Karma

This is a quick look at how the laser scan effect can be implemented in Solaris and tested with both Redshift and Karma.  In this video, I go through Redshift, in both the OBJ and Solaris contexts and lastly Karma XPU.

This is focused on implementing the previous laser scan effect in t...

Knitting, Weaving and Patterning on 3D Surfaces

In this tutorial, you'll learn how to transfer over all of the previous weaving and knitting techniques so that they can be applied to any 3D surface.

This technique uses the UV's to move any curves or geometric patterns to the 3D surface using VEX.  Special attention is pai...

Weaving, Ribbed Knit and More Textile Techniques

In this tutorial, I show how a basic knitting style covered previously can be extended to produce more complicated knit, woven and lattice fabric  structures.

Knitting Fabric Textile Tutorial

Hope you enjoy this 2 part knitting lesson, this covers the basic of generating knitted curve structures using highly modular and flexible approaches.  These base curves are then used to generate individual fibers that make up the yarn which produces a highly detailed and fuzzy look.  &...

Printer Papers Part 4 | Final Delivery, Post Production, Editing, OCIO and ACEScg

In part 4 of this series, I cover the ACES color profile and how it can be ap...

Printer Papers Tutorial Part 3

Part 3 of this series is ready!  Finally some of the fun stuff :D (lighting, shading and rendering)

I cover how to build out the paper shader for Karma XPU, override texture maps for front and back faces as well as override other aspects of the scene on a shot by shot manner...

Printer Papers Tutorial Part 2

Part 2 of this multipart tutorial breaking down my papers project 

This covers creation of motion paths for all the papers, how these motion curves can be used in Solaris to create procedural camera rigs and creating ...

Printer Papers Tutorial Part 1

Part 1 of this multipart tutorial breaking down this project https://youtu.be/UmeqVHc9_HA

This covers .usdz import of the printer geometry, collision proxy generation as well as vellum simulation set up, emittin...

Adidas Color Slice Effect Part 2

Back with part 2 of this tutorial!

This time covering coloring, shading, rendering and lighting side of things, everything done in Solaris with KarmaXPU.

Karma and MaterialX seem to be pretty powerful with a bright future ahead of them. The standard surface is much better t...

Adidas Color Slice Effect

Hello everyone, I really appreciate your continued subscriptions and support :)


This is part 1 of a tutorial showing how to make this kind of logo animation you might see at the end of an advertisement.

Covered here is the geometry (SOP) portion, part 2 will cover lighting and sh...

Torus Knot Braiding (Scene File & Walkthrough)

Hello, these are some additional techniques I wanted to share that are related to the previously posted curve braiding tutorial.

This is building on the concepts that are covered in the tutorial and looking at how you can further customize aspects of the braiding technique.

Curve Braiding Tutorial

Building on the techniques from the rope tutorial, we're moving on to braiding techniques.

Learn how VEX can be used to create "over under" basket style woven threads.

Point attributes are also used to further enhance and shape the weave.

Any rem...

Tutorial: Twisted Rope

Hello!  Thanks to everyone that's stuck around during the lull in content.  I was busy with a few different projects at work that were overlapping on deliveries as well as moving.  Hoping to have for time going forward and get into some similar topics such as yarn, knitting, knitti...

Tutorial: Vellum Caged Inflation

Hello, I'm happy to share my first step by step tutorial.  In the past I've shared some walkthroughs breaking a scene but I feel that this may be easier to follow along with for most people.

Please let me know what you think about the depth and duration of this type of tutor...

Wedging Inflated Balloon Generation with TOPs

This setup builds on the previous balloon bash setup so feel free to reference that setup if your interested in a deeper look into the Vellum constraints and specifics behind the inflation simulation.

Here, we're basically extending the Vellum-drape inflation process to work over...

Balloon Bash

I've been starting to experiment with cloth modeling using the Vellum solver.  This is a bit similar to the Marvelous Designer workflow, where the fabric is laid flat and then sewn together during a simulation which allows the fabric to produce all the nice wrinkles, folds and bulges that ma...

Rose Blossom Rig / Simulation

Apologies for my hiatus from posting!  I'm hoping to get back in the swing of things now and have some really exciting stuff I've been working on to share with you.  I really appreciate everyone's continued support and for sticking around :D


This is one of the most challengin...

Procedural Succulent Plant Rig

In this setup we use KineFX joint chains (https://www.sidefx.com/docs/houdini/character/kinefx/skeletons.html#turning-a-polygonal-line-into-a-joint-chain) to rig and animate a succulent pla...

Phyllotaxis Flower Blossom

I wanted to expand on the previous setup and possibly do a little series of techniques revolving around plants and getting into more advanced aspects including simulation, shading and rendering.  (The last two images are reference photography that I used to inform this technique)

Plant Phyllotaxis with VEX

In the spirit of the beginning Spring (for us on the Northern Hemisphere at least), I thought I'd share a simple and straightforward way to generate these plant seed arrangements.

I find this really handy to have on hand for tons of procedural modeling and effects setups so I've ...

Illusion of the Sweep

Continuing our explorations of the new Sweep and Orientation Along Curve nodes, I came up with these hypnotic spinners :)

You can get some really complex results by feeding the  results of one Sweep operation into another Sweep node.  Check out the file, each one is a s...

Twisting Ring of Spheres

I wanted to find a really simple way to recreate these kinds of animations with Houdini
