Render another test frame
Use the File > Quick Render menu item to render another test frame into the Camera viewing pane. Notice how the surface appears to be bumpy. This is what a bump map does. Click the mouse to return to model mode.

Render your final animation
Use the File > Render Setup (Command-U) menu item to open the Render Setup dialog. Enable the Range of Frames option and click OK.

Use the File > Final Render menu item to render your animation to disk. In the Save dialog use the New Folder button to create a folder inside your RollerCoaster folder. Name it Frames. Set the file name to Frame and click OK. All of the frames for your animation will be rendered and saved with a numerical extension indicating the frame number of that image. After rendering, use the Utilities > View PICTs tool to playback your animation. Select the first frame and click OK.
