Composite Mapping

A composite map layers two or more texture maps onto one another, in order to produce a more detailed image.

The end result is determined by the level of transparency defined for each layer. Transparency can be global (applied to the entire surface of the layer), derived from the layer’s alpha channel, or based on a mask. To fine-tune the image, the pixels of each layer can also be blended with one another in a number of different ways.

In this tutorial, you will create a complex texture map of a steel shutter for a pawn shop. The map will consist of five layers of images composited together using various transparency settings and blending techniques.
