From the developer:
The Material Editor provides functions to create and edit materials and maps. A material is data that you assign to the surface or faces of an object so that it appears a certain way when rendered. Materials affect the colour of objects, their glossiness, their opacity, and so on. The images or procedural effects you assign to materials are called maps.
