VFX-sketchbook-Godot-3.x is an experimental playground project for exploring and creating visual effects using Godot 3.x's VisualShader system. Designed as a sketchbook or sandbox environment, it serves as a collection of visual effect experiments and shader prototypes. The project is publicly available for anyone interested in inspecting, learning from, or building upon the work. It is primarily intended as a personal creative exploration space rather than a production-ready tool, making it useful for game developers, technical artists, and shader enthusiasts who want to study VisualShader techniques and VFX approaches within the Godot game engine.
