Real-Time PBR Material Studio & Shader Lab
Master the optics of light and matter. Fine-tune microfacet roughness, dielectric Fresnel reflectance, and transmission in a live interactive viewport.
Key Architectural Capabilities
Physically Calibrated Optics
Built upon the Cook-Torrance microfacet specular model and GGX normal distribution function.
Real-Time Shader Feedback
Watch specular highlights broaden or sharpen dynamically as you slide roughness from 0.0 to 1.0.
Dielectric Non-Metal Safeguards
Visual indicators alert you when metalness values exceed physically realistic thresholds for organic surfaces.
Transmission & Refraction
Simulate icy translucent rubber outsoles and glass elements with physical depth absorption.
