Camera Silhouette

Quick Tip

In this quick tip I show you how get the camera silhouette of a 3D object, not to be confused with getting the Fresnel or facing ratio. With this technic you can output a distance from edge on the 3D geometry, output a flattened card with a clean mesh of output a polyline.

Tearing Vellum Grain

Tearing Vellum Grain

Tearing Vellum Grain

Part 1

In part 1 of this tutorial I will show you how to simulate a tearing jelly like mass using vellum grain. I'll show you what constraints you need and what gotcha to watch out for.

Part 2

Custom Stitch Setup

in this video we will be using VEX to build our own custom stitch constraints to glue the grains together. In the process I will setup another simulation using different setting to get a different look to the simulation than the first one.

Part 3

Meshing

In part 3 we will look at how to mesh the simulations we have using the constraint network.

Crown Splash From Scratch

Crown Splash From Scratch

Crown Splash From Scratch

In this tutorial I show you how to setup a crown splash from scratch with FLIP fluids in Houdini.
I have made a few tutorials about small scale FLIP fluids and surface tension in the past but this has been requested a couple of times and even if you watched the other ones I think this is useful to get a better understanding of how to control your small scale simulations.

POPs Custom Shield Force

POPs Custom Shield Force

n this tutorial I'll show you one way of setting up a custom shield force in POPs using a combination of force fields setup in SOPs and updating point positions in POPs.
Little glitch in the middle of the recording so sorry about that! But I point out what has been skipped.

Tutorial: Vellum Grass – Basic Plasticity

Vellum Grass

Basic Plasticity

In this tutorial I create a grass patch in sops and simulate it with vellum as hair strands. I then go through using plasticity to make the grass stay in place when bent by collision objects. As a bonus I also turn the collision object into a dynamic vellum object at the end.

Quick Tip: Mask Surface Tension

Quick Tip

Mask Surface Tension

In this video I show how you can mask surface tension using a volume field from SOPs. In it I demonstrate two ways of getting SOP data into the DOP network and how to get it to affect the simulation.
