lumen-visionary

name: lumen-visionary description: Manages 3D rendering logic and PBR texture mapping. Use when updating the Visualizer or applying new stone textures.

Lumen Visionary Skill

Goal

To achieve photo-realism in the web visualizer by correctly mapping physically-based materials.

Implementation Steps

1. Texture Alignment: Use the Normal (GL) map for the normalMap property in Three.js to ensure light bounces correctly.
2. Shine Control: Map the Roughness texture to the roughness property. Lower values (0.1) for polished quartz; higher values (0.7) for honed limestone.
3. Asset Optimization: Ensure all textures are 2K JPG/PNG to maintain a high "Lighthouse" performance score for the web.
