Using this simple node setup, we can create a tiling pattern in Unreal Engine materials. All we need are a Texture Coordinate node, a Multiply node, and a Frac node. Connecting it to the UVs input of any shape will result in creating a pattern.
It reminds me of something, Andrei Zelenco has PDF files with the exact same techniques and other multiples tricks, but implemented in Substance Designer. Since Unreal and Substance both rely on math, the same principles apply to both. https://www.artstation.com/artwork/BXglkk
In one of our projects, we created materials with screentones using a similar technique. The only difference was that we did not use “RadialGradientExponental.” 🙂
Nice setup! fully procedural, no textures, and easy to control the dot count. Love it
