Resources And Further Reading
reference~6 min readreviewed 2026-07-05
We never stop learning. Here are some of the resources I have used over the years that have proved very useful. Keep them bookmarked.
3.1Online Learning
Shader And Graphics Programming
- The Book of Shaders - a friendly, interactive way into GLSL fragment shaders. Start here if shader math still feels foggy.
- Catlike Coding - Jasper Flick's Unity tutorials on rendering, shaders, procedural generation, and math. Clear, deep, and very easy to come back to.
- Alan Zucconi - visual explanations of shaders, volumetrics, color, and procedural techniques.
- Shadertoy - a browser playground for GLSL. Great for pulling apart how other people solve visual problems.
- GPU Gems (NVIDIA) - the classic free series on rendering, simulation, and GPU programming. Some chapters are old, but the thinking still holds up.
Video Channels
- Ben Cloward - detailed node-based shader tutorials for Unreal and Unity, beginner to advanced.
- Tech Art Aid - focused Unreal tech-art tutorials - materials, Niagara, Blueprints, optimization.
- Simon Schreibt - Game Art Tricks - breakdowns of clever real-time rendering tricks from shipped games.
- Freya Holmer - beautifully visualized math and shader tutorials - Beziers, splines, lighting, SDFs.
Rendering And Pbr Theory
- Real-Time Rendering (site) - the companion site for the book, with a big list of rendering links worth exploring.
- PBR Book (pbrt) - Physically Based Rendering, free online. It gets deep, but it is brilliant when you want to understand why light behaves the way it does.
- Filament Material Guide - Google's practical PBR docs. Very useful for metallic/roughness workflows.
- LearnOpenGL - a steady path from basics through PBR, IBL, shadows, and deferred rendering.
3.2Communities And Forums
- tech-artists.org - still one of the best places to find TA discussion, Slack links, jobs, and people who have solved the weird thing you are stuck on.
- Polycount - long-running game art community for modeling, texturing, shaders, and portfolio feedback.
- realtimevfx.com - the place to learn from real-time VFX artists working with Niagara, VFX Graph, shaders, and particles.
- Discord - Unreal Slackers, the Houdini Discord, the Unity Discord, and The Art of Tech Art are all worth having around.
- Reddit - useful in patches: r/gamedev, r/unrealengine, r/unity3d, r/GraphicsProgramming, and r/technicallyart.
3.3Gdc And Conferences
- GDC Vault + YouTube - archives of GDC presentations - search "technical art", "rendering", and "pipeline". The Technical Art Bootcamp track is consistently valuable.
- SIGGRAPH - Advances in Real-Time Rendering - the annual course featuring cutting-edge rendering work from major studios. Essential viewing.
- Graphics Studies by Adrian Courreges - frame-by-frame breakdowns of how commercial games render a single frame.
- Unreal Fest / Unity Unite - engine-vendor talks on Nanite, Lumen, Niagara, PCG, HDRP, and production workflows.
- Everything Procedural Conference - the annual community conference (Breda, Netherlands) built entirely around procedural content generation for games - Houdini and PCG pipelines, tool authoring, and terrain/city/foliage systems, with talks from studios and indies. Recordings usually land on YouTube afterwards, so it's worth following even if you can't attend in person.
3.4Documentation
- Unreal Engine Documentation - rendering, materials, animation, Blueprints, C++ API, and every subsystem.
- Unity Manual & Scripting API - shader reference, render pipeline guides, scripting API.
- Houdini Documentation - SOPs, VEX, HDAs, and Houdini Engine integration with game engines.
- Substance 3D / Maya / 3ds Max / Blender docs - the DCC references you'll keep open in a tab forever.
- Shader language references - HLSL (Microsoft), GLSL (Khronos), Metal (Apple).

The best resource is the one you actually open. Pick a couple from each category, use them properly, and come back to this list every now and then. It reads differently as your own work gets deeper.
