Scene 1: Rendering

Rendering the result

As mentioned earlier, it's important to check your work with a production rendering. This time you use a toolbar shortcut.

On the Rendering tab, click Quick Render. This uses the current settings in the Render Scene dialog and begins to render immediately. The keyboard shortcut for this is SHIFT+E.

As you can you see, the result is quite a bit different than the smooth, orange sphere with only a Diffuse map applied.

9. When a material is in the scene and in the material editor, but the object is not selected in the scene, the corners are hollow.

10. In the material name field, highlight the default name. Type Orange Peel and press ENTER to rename the material.

11. Click the Blinn Basic Parameters rollout to close it. Then click the Maps rollout to open it.

Notice that the Diffuse channel, which shows the principal color of an object, is checked. Its Map button lists the map you applied earlier, orangetex.gif.

12. On the Maps rollout, drag the Diffuse map (orangetex.gif) to the Bump channel. The cursor is an arrow with a box attached. Position the arrow over Bump and release.

The Copy (Instance) Map dialog is displayed.

13. Click Instance and then OK.

The choice of Instance means that if you switched to a different map in the Diffuse channel, the same map would be used in the Bump channel. If you choose Copy, the Bump channel wouldn't update.

14. Set the Amount field for the Bump channel to 100.

The minus value indents the lighter areas of the map into the surface, as you'll see when you render.

15. Using the standard Window control at upper right, minimize the Material Editor for later use.
