Procedures
To select a bitmap image for a map:
In the Material Editor, go to a component's tab.
Click Open New Map File.
This assigns a map to the component. For example, clicking Open New Map File in the Diffuse tab creates a diffuse or "texture" map.
In the Select Bitmap Image dialog, navigate the Look In field to select the appropriate directory.
Highlight the file name in the file list window.
Click Open to close the dialog.
