Strategic Objectives
• Master the physics of BSSRDF for hyper-realistic skin rendering.
• Understand the multi-layered biological composition of human tissue.
• Implement advanced light transport algorithms in modern render engines.
• Capture the subtle nuances of melanin, blood flow, and hydration.
The Core Challenge
Digital characters often look like plastic or stone because light doesn't just bounce off us—it lives within us.
