to a lens flare property and the preview window is active, the preview updates automatically. A white line at the bottom of the main preview window indicates that it is updating a change made within the lens flare dialog. Preview When you click the Preview button, the window displays your flare in the upper left corner if your flare has automatic or manual secondary elements. If your flare does not contain these elements, the flare is centered in the preview window. If the VP Queue button is not on, the preview displays a generic flare to which you can make adjustments. Each time you change a setting, the preview automatically updates. A white line appears at the bottom of the preview window to indicate the preview is updating. Update Redraws the entire Main Preview window, as well as the smaller windows each time you click this button. This function is critical when you need to view changes you have made in the Video Post queue, such as moving the Time Slider to a different frame, changing your geometry or a light, or changing another filter that precedes the current one in the Video Post queue. The VP Queue button must be on to preview the contents of the Video Post queue. In this case, clicking the Update button causes a small dialog to appear, with an indicator showing the progress of the update. VP Queue Displays the contents of the Video Post queue in the main preview window. The Preview button must also be turned on. Rather than having to test render every time you want to see the result of the effect in the scene, VP Queue displays a final composite, combining the effect you are editing with the contents of the Video Post queue. NOTE If you leave the Preview and VP Queue buttons active when you exit Lens Effects Flare, it will take several seconds to re-render the scene in the main preview window the next time you start Lens Effects Flare. The view in the main preview window also depends upon which lens flare options you have set in the Preferences panel on page 6854. Lens Flare Properties group Specifies global settings for the flare, such as the source for the flare(s), the size, seed number, rotation, and so on. Seed Gives the random number generator in Lens Effects a different starting point, which creates slightly different lens flares without changing any settings. Using Seed guarantees a different lens flare, even if the differences are very small. For example, if you set up a ray effect for your lens flare, you will get slightly different rays in the lens flare if you adjust the seed value. Lens Effects Filters | 6851
