Dear Patrons,
Today I want to announce that I am currently working on a new episode for the Vellum playground course. In this episode we will learn different techniques to art-direct splash simulations with Vellum Fluids.
The first part will show how to procedural model a strawberry and then we will dive into velocity field creation to guide fluid simulations. That´s gonna be a cool one, so stay tuned.
Thanks for your support!
Best regards,
Roland

In episode five of our Houdini course, the Vellum Playground, we will look at advanced cloth tearing techniques.
We'll begin with a simple cloth simulation. We will define an initial state for the simulation, after which we'll use weld constraints to break our flag apart. I'll demonstrate several ways to control the tearing with attributes., including t what point in time the the cloth tears. Using the pyro source spread node, you'll learn how to create an infection simulation that can ...

Learn how to create glue constraints between objects during a Vellum simulation. Let’s create this funny cannon, shooting sticky balls onto a soft body target.
In this lesson you will learn how to create new constraints during a simulation. We will also cover how to break these constraints. Visualizers help us to create exactly the behavior that we expect.

We can give our cat the finishing touches by setting up a studio backdrop, lighting, materials, and a final render with Redshift.
We will start by creating a modifiable studio backdrop that we can later use for other projects. We’ll also learn how to add and position lights and a camera. We’ll take a quick look at Redshift and its basic settings to finish off the final animation.
