We’ll start looking at Physical Based Rendering in Action. The point of Physical Based Rendering (PBR) is that it simulates the natural interactions of light rays and real world materials. This allows for consistent and predictable results with textures even if the lighting conditions are changed in the 3D environment. PBR is normally combined with image based lighting which allows the textures to pick up the colours from a surrounding environment. So even if the lighting is day or night, indoors or outdoors - You’re able to create realistic results quickly in Action.
