Utilizing realistic materials and lighting models to simulate the physical properties of surfaces, PBR (Physically Based Rendering) enables assets and tools to achieve consistent, lifelike appearance across different environments and lighting conditions. Commonly employing texture maps such as albedo, normal, metallic, and roughness, this approach aids in accurately depicting how light interacts with various materials in 3D projects.

Utilizing content created by algorithms rather than human made content. Often utilizes a "seed," a relatively small string that is used to control the randomization algorithm that generates the entire world.
