Lumina Workbench - Visual shader editor with AI — describe materials, get code

by•
Lumina is a visual shader node editor for creating PBR materials. Describe what you want in plain text — AI generates the shader graph. Export to Three.js, Unity, Shadertoy, or raw GLSL. Real-time 3D preview included.

Hey Product Hunt! 👋 I'm thrilled to launch Lumina today! As a tech artist, I was frustrated with the gap between visual shader editors (too limited) and writing raw GLSL (too technical for quick iterations). So I built Lumina — a hybrid approach where you can: 1. Build shaders visually with 77 node types 2. Let AI generate graphs from text descriptions 3. Export directly to your favorite engine The AI doesn't just generate random code — it uses a structured GraphOps protocol to build valid, optimized shader graphs every time. Would love your feedback! What export formats would you like to see next? Unreal? Godot? Thanks for checking it out! 🙏
