Copy To Points Randm Input
Introduction Here’s a very simple but quite useful tip for Houdini, let’s say you are working on a landscape and you want to scatter some random rocks on it, in this post I’ll show you how you can do that! To achieve this we need to give a unique ID attribute for each object you want to…

Perfectly Remapping a Cube to a Sphere
A perfectly rounded sphere, with clean and uniform topology. I’m sure every artist who works with 3D models needs something like this at some point.We all went down the route of subdividing a cube multiple times, but that doesn’t translate to a perfect sphere: A good workaround would be to reproject the geometry of the…

Linear & Smooth Step – Material & Niagara Functions
Intro In this blog post, you will find a brief explanation of how these two functions work and their application, I will mainly show the setup of how they can be created as Material and Niagara functions in Unreal Engine. I started looking into this because I needed a Smooth Step Function to use in Niagara and I couldn’t find a built-in node…

Gradient Visualizer Material Function
Similar to what I’ve done in Substance Designer to visualize the Smooth Stepping Curve Function I made. I created a Material Function in Unreal Engine to use as a tool to visualize sine waves or any gradient I use in my materials for various FXs. If you think this could be something useful, you can find…

Hologram Shader
Realtime FX This is a Hologram Material I’ve done almost three years ago, it was a good way to explore how to use and manipulate sine waves, as well as create some useful functions.I tried to make it as modular as possible so that different sections can be pulled out and recombined in other materials,…

Triangle Wave Function/Modulation
The triangle wave function it’s a cheaper alternative to a sine wave, it can be very useful as the alpha input for a lerp node when working with materials or FXs.In some cases, it might be exactly what you’re after since it allows you to blend between two inputs in a linear way. This is what a remapped 0…
