After loading the scene into DP, the following box appears:

We can select or modify the properties of the materials we have attached to the objects previously in Maya. After selecting a material we can define the color (C), bump (B), glow (G), specular (S), and opacity (O) components, and can also resize, rename it.

The UI pretty much similar to the Abobe software's user interfaces, althoug there are some key differences. At the bottom of the Tools panel there are the material components (color, bump, and so on), so when we select a brush or eraser, we have to select which components do we want to paint/erase on.

On the right handside of the screen is the Command Panel. Under the Elements (F7) section we can change the material and object properties. The first tab in this section - named as Layers - will contain the C,B,G,S,O (color, bump,...) segments of the material. We have almost the same possibility to build up complex layered textures as in Photoshop. Just a click on the white box under the C(olor) letter could result a color layer.....(and so on). We can assign a transparent layer, a solid color layer or an image to the definied channels.
