In part two of our tree rig series, we’ll build a working rig for our tree, add large scale wind animations onto it and capture the trunk, branches and twigs.

KineFX 101 – pt. 30: Tree Rig 01: Generating a Tree

Welcome to our second huge nature setup in KineFX. Over the next two weeks we will build a tree swaying in the wind and develop techniques to add lots and lots of detail while keeping our setup fast and art directable.

This is a four part se...

Advanced Setups 23 - Controlling Stable Diffusion With Houdini

Of course Mo could take the high road and build a stable diffusion pipeline using Huggingface’s Diffusers library… But let’s not kid ourselves. Thanks to 2023-03-09 18:11:43 +0000 UTC View Post

KineFX 101 – pt. 29: Rigging Volumes

Lets face it: One of the really fun things with KineFX is just finding new, weird things to rig and animate. And … why wouldn’t you want to rig a volume?

This is our challenge for today and the solution is a really simple and straightfor...

Geometry Nodes Ep22 – Coloring the Yarn Sculpture

This time we sample the weights of the original points as a basis for colorizing the connecting yarns.

Geometry Nodes Ep21 – Creating the Second Layer: The Yarn Sculpture

Finally it’s time to implement the second layer of our Mograph effect: The yarn sculpture. Utilizing the “plexus” technique, as AE users would refer to it, we’ll fill the psyche model with points and connect these with lines controlled by ...

KineFX 101 – pt. 28: Building a Curve Controller for KineFX

We’ve all been there: You just spent hours upon hours building, recording and editing a huge five part series on building a flower inside Houdini and you look back and think: Maybe controlling *everything* with ramp parameters wasn’t that grea...

KineFX 101 – pt. 27: Flower 05: Fur, Karma and Variations

Welcome to the final episode of the flower mini series. Today we'll start by adding some fur to our stem, going over the render settings in Karma and finally build the other two flowers you know from the bouquet shot of the teaser.

Geometry Nodes Ep 20 – Implementing a Linear Falloff

In this video we’ll learn how to solve the issue with the spherical falloff, that the object reappears as soon as the falloff gizmo crosses the object. Using a vector dot product we’ll implement a linear falloff that uses a line as a gizmo to ...

Advanced Setups 22 – Jeroen Claus: Comparing Clustering Algorithms

Thrilled to have Jeroen Claus back again for this final video in his series on clustering algorithms, this time comparing the techniques we covered so far.

Go check out Jeroen's Work: 2023-01-19 16:59:14 +0000 UTC View Post

KineFX 101 – pt. 26: Flower 04: Blossom Animation

Welcome to episode 4 of 5 of the flower mini series. Today we’ll connect all the bits and pieces we built over the last three episodes and rebuild the first part of our teaser animation: A flower opening! We also can finally make real use of the...

KineFX 101 – pt. 25: Flower 03: Extra Bits

Welcome to episode 3 of 5 of the flower mini series. Today we build all those little extra bits that make a flower. Those are the small, green fleshy leaves at the bottom of the blossom, the central seed pods and of course the stem.

KineFX 101 – pt. 24: Flower 02: Blossom

Welcome to episode 2 of 5 of the flower mini series. Today we take the single rigged petal from episode 1 and turn it into a full blossom. We’ll use rig attrib wrangles, inverse kinematics, vellum and a few other tricks to give you all the tools...

KineFX 101 – pt. 23: Flower 01: Petal

It's finally time to build a big rig. A really big rig. Over the next 4 to 5 episodes we will create a flower setup that is completely build around KineFX. This means you get a fully rigged flower in the end, which is fully compatible with rig pos...

KineFX 101 – pt. 22: TD Techniques: Copy Rigged Characters

We need to take a look at something that seems easy, yet is surprisingly difficult: Creating copies of a rigged character with either a Copy To Points or Copy And Transform SOP. This tutorial will show you how you can fix all problems that will ar...

Advanced Setups 21 - Jeroen Claus: HDBSCAN

Jeroen Claus covers another important clustering algorithm in the thrid part of his series on popular algorithms used in data analysis and visualisation. In this episode he’ll co...

KineFX 101 – pt. 21: CFX Fur – Part 2: Using and Misusing Fur Nodes in SOPs

In this episode we’re finishing our look into the Houdini fur workflow by building a complete fur setup just using SOPs and finding some new applications for it outside of character fx: Using Guide Process nodes to create organic looking splines...

Advanced Setups 20 – Jeroen Claus: DBSCAN

Jeroen Claus continues his series on popular algorithms used in data analysis and visualisation. In this episode he’ll cover a more capable algorithm than your grandma’s k-Mean...

KineFX 101 – pt. 20: CFX Fur – Part 1b: Karma Hair Procedurals
