Beginner
Who this is for.
Godot enthusiasts who want to learn shader language step by step.
Game developers looking to improve the graphics of their games.
Artists who want to transition into technical art for Godot game development.
Designed for both absolute beginners and seasoned developers, this in-progress project aims to deliver 300 pages on shaders — from the ground up — with no prior experience required. You'll learn the fundamentals of Godot’s shader language, master essential math concepts, and gain a clear understanding of rendering pipelines in a beginner-friendly manner. You’ll progress from simple color tweaks and basic shapes to complex effects like water, stylized shading, and screen-space VFX in both 2D and 3D. Dive into lighting models, vertex manipulation, particle systems, and even compute shaders — all through practical, step-by-step examples that reflect real-world game development scenarios.
