To learn the basic principles of Combine to Layer, we recommend you read the 'Combine to Layer: Controlling overprinting layers' article. This article aims to teach you how to use the various features of the Combine to Layer Window to help develop textures.
Using Combine to Layer to balance textures
In the design and development of textures, different transparencies may be used for individual layers. In the example below, an opaque white layer is used. However, we can save on the cost of production if we simply build this effect into the design, by taking information away from the other layers, where this opaque white sits over then. the movie below explains how:

The Combine to Layer Window can also be used to add the information from some layers while taking the information away from other layers at the same time. The movie below explains how:
Troubleshooting Combine to Layer
If Combine to Layer is not working as expected, you may have forgotten to press 'Make' at the bottom window first. Therefore, activate the layer you want to edit (click on its pencil icon in the Layers Palette) and then click the Make button in the Combine to Layer Window. A preview icon will appear on the layer chip in the Layers Palette.
Also check that no other layers are active. If more than one layer is active in the Layers Palette, the Combine to Layer Window will be empty.
Use the keyboard shortcut ⌘D to ensure no hidden selections are in the file.
