Math Essentials for Tech Art in Unreal Engine

This tutorial series covers the essential math for game art. It’s full of practical solutions for material nodes & procedural generation (Construction Script). I took the most popular use cases that I’ve encountered as a Lead Technical Artist in games. Finishing the course will give you practical experience for the games industry.

Material and Blueprint nodes are explained through popular examples, which you’re likely to encounter in everyday tasks. Whether you’re a programmer, an artist or a tech artist in need for a recap – you will find a useful tip for sure!

I divided the topics into concise, 10 to 20–minute long tutorials. They’re brief and packed with knowledge, coming from over a decade of my experience in game development.

Learn how to use dot product in Unreal materials. Create a ghost effect, procedural snow layer, fake directional lighting and a silhouette glow.

Learn how to mix values, blend textures and interpolate object transforms with lerp.

Use sine for a pulsing material, wave masks and a flickering light with emissive glow. Learn how to animate material and light color over time – in sync with Blueprint.

Rotate UV maps or any 2D vectors with sine and cosine. Use sine for a flickering light in Blueprint, with animated material and synchronized light color. Learn about performance cost of sin/cos nodes. Are they worth replacing with smoothstep (Hermite) approximation?
