    Introduction In this post, I would like to outline a technique I frequently use to debug the look of a gradient, as well as trying to take it further by exposing some extra controls to increase its usefulness.I’ve been inspired, for a while now, to try and recreate, within Unreal’s Material Graph, something similar to…

    Introduction In this blog post, I’ll go over how you can sample a texture in HLSL, more specifically, in a Custom Node Material Graph of Unreal Engine.I won’t be only showing the code itself, but how you can find it out on your own, as well as doing a little breakdown of the function that…

    Introduction This post is not a step-by-step tutorial, but more like a documentation of a Material Function I created. However, it does contain screenshots of the entire graph, so feel free to recreate your own version. I’m currently working on a simple billboard baker that bakes the various GBuffer layers as textures using Render Targets,…

    Volumetric Clouds A Clouds Material exploration I worked on when UE4.26 was released with the new Volumetric Cloud component, which is able to interact with Sky Atmosphere, Sky Light, and directional light. The Material is divided into two main layers, one is using a volumetric texture to define the main shapes and details of the…

    Material Function Library UE5 The last piece of my 2D SDF library.All of the advanced shapes you can see in this post are coming from Indigo’s Article (+ShaderToy), please check it out:2D distance functions I’ve only recreated them in Unreal’s Material Graph using nodes, it was a lot of fun and a great way to…

    2D SDF – Gradient/Flowmap and AA technique – Material Function Library

    in ,

    Introduction In this post, I’ll show you how you can create a gradient from a 2D SDF and how it can be used as a flowmap in the material to warp a texture or in Niagara to drive the location of particles! I’ve also added a bonus section about Anti Aliasing, something that I haven’t covered before.If you haven’t seen…

    Material Function Library UE5 This is the Second Part of a 2D Sign Distance Field Material Function Library I created for Unreal Engine.SDFs can be used in various different ways, in this case, they are very powerful and useful when creating materials. Here you can see different ways shapes can be combined.Check out the blog…
