An SBS file contains a substance package created by Allegorithmic Substance Designer (Adobe Substance Painter), a program used to create materials for use in 3D content, such as animations, special effects, and video games. It stores a graph with nodes that visually represent the properties of the 3D material. SBS files also include all the resources that make up the 3D material. source

Shading refers to the depiction of depth perception in 3D models or illustrations (in visual art) by varying the level of darkness. Shading tries to approximate local behavior of light on the object\'s surface and is not to be confused with techniques of adding shadows, such as shadow mapping or shadow volumes, which fall under global behavior of light. source
