A daily sun study moves the sun across the sky on a given day to show how the shadows change throughout the day.

View a daily sun study animation.

1. Set the location for your sun study animation. From the Raytrace menu, click Sun, and set the location in the Place tab.
2. If you want more realistic lighting, be sure Automatic Sky is turned on: From the Raytrace menu, click Environment. In the Main tab, select Automatic Sky.
3. Click then click .
4. At the Date for all frames prompt, enter a date. The most reliable format for entering the date is ?0-Jan-2002? This avoids the incorrect interpretation of ?/10/2002?which is January 10^th in the United States, and October 1^st in most of the rest of the world.
5. At the Start Time prompt, enter the time for the first frame.
6. At the End Time prompt, enter the time for the last frame.
7. At the Number of Frames prompt, enter the number of frames you want in the animation. If the start time is 8:00 am, and the end time is 8:00pm, and you want frames every hour, you need 13 frames (not 12 -be sure to count both the first and last frames, in addition to the frames in between).
8. At the File type prompt, enter the type of file you want to create for each frame of the animation. Choose from JPG, BMP, PNG, or TGA. If you see an option for GIF, do not use it ?it will not work.
9. At the Viewport name to render prompt, type the name of the viewport you want to animate. The default is the Perspective viewport.
   
   If the viewport name contains spaces, be sure to surround it with quotes (eg. "My Viewport") when you type it.
10. At the Animation sequence name prompt, type a name for the animation sequence. This name will be used to name the files in the animation, and for the HTML animation preview page that is generated as part of the animation.
    
    For sequence names with spaces, surround the name with quotes (eg. "My Sequence") when you type it.
11. Next step, Render the Frames.
