Tutorial products and Unreal Engine project files from Tech Art Aid.
Unreal Engine Project Files#
This is a raw copy of the Unreal Engine 4 & 5 projects used in some of the tutorials on the Tech Art Aid YouTube channel.
What's included
The archive contains all the levels (.umap) and assets (.uasset) — textures, models, materials and Blueprints — presented in the following Tech Art Aid YouTube tutorials:
- How to fix translucent materials (dithered opacity)
- Stylized colors using gradient mapping
- Stealth Invisibility Effect (With Distortion)
- Detailed Texture Blending with HeightLerp and Vertex Painting
- Dynamic Texture Coordinates (Animated, Generated UVs)
- UE4 Optimization: Instancing
- Good-Looking Randomization for Procedural Buildings
- Making Tools for Level Art in Pure UE5 (only Blueprints, no 3rd party assets)
- Making Tools in Blueprint with Editor Utility Widgets (only Blueprints, no 3rd party assets)
- Volumetric Materials Part 1 & 2
- 2D Shadows Using Signed Distance Fields
- Porting ShaderToy Code to Unreal
- Audio Visualization
- High-Quality 2D Shapes in Materials by Using SDFs
- Material Tricks for Instanced Static Meshes
- And more — for example, most of the Twitch streams so far.
Not included: third-party content (Megascans, Epic example files) and source files such as uncompressed textures or editable 3D models.
On June 1, 2021, I made the old project compatible with Unreal Engine 5 too. Download the appropriate ZIP file for your engine version.
Math Essentials for Tech Art in Unreal Engine#
A practical maths series for technical artists working in Unreal Engine. It turns familiar Material and Blueprint nodes — Dot Product, Lerp and Sine — into the effects and tools you are likely to make at work. Artists, programmers and technical artists should all find something immediately applicable.
Included videos
Four Full HD .MP4 tutorials with complete English commentary:
- Dot product (16 min): ghost transparency, a procedural snow layer, fake directional lighting, silhouette glow, desaturation and oversaturation.
- Linear interpolation (20 min): mixing values and colours, texture blending with HeightLerp, Blueprint instancing, transform interpolation, landscape tiling and camera-depth remapping.
- Sine (7 min): pulsing emissive materials, wave masks and keeping animated material and Blueprint light colours in sync.
- Advanced sine (15 min): flickering lights, noise equations, Math Expression, rotating UVs, and the performance trade-off of sine/cosine versus a smoothstep approximation.
