Materials

Materials define the appearance of 3D model surfaces and how they react to light. Without materials, models are simply shapes, blank canvases.

Materials can affect both the geometry of a model (vertex shading) and its colors (pixel shading).

You can use multiple material layers to build more complex materials.

In practice, materials generate partial definitions of shaders integrated as part of the shading of models (lights and shadows).
