When you bake textures (render to texture), you have more control for how the baked texture displays in shaded viewports. You set these in the Output rollout of the Render To Texture dialog. Using the Target Map Slot assignments, you can specify in detail which maps will be rendered to which slots of the existing material.

Note: The first time you use Render To Texture, all Target Map Slot assignments are blank. After you set them and render the baked texture, those settings become the default Target Map Slot settings for future modelling sessions. Autodesk VIZ stores the Target Map Slot assignments in the texturebake.ini file in the \VIZ2008\plugcfg folder.
