Physically Based Rendering (PBR) is a rendering technique that aims to simulate light behavior in a realistic way. Unlike traditional rendering methods, PBR uses real-world physics principles to determine how light interacts with surfaces.
PBR materials are essential for creating believable 3D environments in modern games and real-time applications. They provide consistent lighting results across different lighting conditions, making assets look realistic whether they're in bright sunlight or dim indoor lighting.
