Lumina Workbench – Visual shader editor with AI-generated PBR materials

Summary: Lumina is a visual shader node editor that uses AI to generate physically based rendering (PBR) shader graphs from plain text descriptions. It supports real-time 3D previews and exports shaders to Three.js, Unity, Shadertoy, or raw GLSL formats.

What it does

Lumina combines visual node editing with AI-generated shader graphs using a structured GraphOps protocol. It offers 77 node types and enables exporting shaders directly to popular engines.

Who it's for

It is designed for tech artists and developers needing a hybrid tool between visual editors and raw GLSL coding for faster shader iteration.

Why it matters

Lumina bridges the gap between limited visual editors and complex GLSL coding by providing valid, optimized shader graphs generated from text descriptions.
