6.2 Setting material parameters
After you create a material, you can set the material parameters in the Model Viewer. More specifically, when you select a material in the Model Viewer, the material properties are displayed in the Properties rollout. Note that materials can have child components, which can be selected by expanding the tree item. The components will have their own set of material parameters that can be altered.
Note that you can assign a color to each material. In the Object rollout on the Model Viewer, you will see a color selector next to the material's name. If you click on this you can change the color associated with that material. When assigning a material to a part (see below), the part will be shown using the material's color.
