The Use Auto Focus setting automatically adjusts the objects within the eld of the lightsviewable area to the maximum size of the shadow map resolution. So if, from the lights pointof view, an object is surrounded by empty space, the light will zoom into the object in the depthmap image.

This helps optimize the use of the pixels within the depth map image so that noneare wasted. Its usually a good idea to leave this setting enabled when using spotlights; however,you may encounter a different situation with other types of lights. Now try this: 1. Set Resolution of the depth map to and Filter Size to 0. Create a test render, and store the image. Create another test render, and compare it to the last render created. The shadow is very blocky when the size of the ground plane is increased see Figure 9.

When usingdirectional lights, the size of the viewable area is always adjusted to t all the objects in thescene. This is because directional lights do not factor in their position in the scene when calcu-lating shadows, only their orientation. In this situation, you can use the new Shadow Map Camera feature described in the mentalray Shadow Map Overrides section.

Viewport 2. This is known as Viewport 2. This modes main advantage is that the performance is improved when viewing scenes with a great deal of complex geometry.

Its also possible to view bump and normal maps covered in Chapter 11 as well as other textures applied to your models. You can also preview depth map shadows cast by the lights in the scene but not ray trace shadows. Ray trace shadows are covered later in the chapter. Inaddition to the Resolution setting, there are also Samples and Softness settings. The Softnesssetting is similar to the Filter Size attribute for Maya shadow maps.

You can click the Take SettingsFrom Maya button to automatically load the settings created for standard Maya shadow mapsinto the mental ray attributes. Open thescene from the directory on the DVD. In the Render Settings window, make sure Render Using is set to mental ray. On the Quality tab, make sure the Quality Presets drop-down is set to Production.

Select the spotlight, and open the Attribute Editor to the spotlightShape1 tab. Scroll down to the Attribute Editor, expand the mental ray rollout, and expand the Shadows section under mental ray. Check the Use mental ray Shadow Map Overrides box. This activates the Shadow Map Overrides section, giving you access to mental ray controls for shadow maps.

Set Resolution to and Softness to 0. Create a test render. Store the image in the Render View window. The render is similar to the results seen beforein other words, its very grainy. Set Samples to 64, and create another test render. The graininess is reduced without sig- nicantly impacting the render time. Store the image in the render view. Detail shadow maps are a more advanced type of shadow map that stores additional information about the surface properties of shadow-casting objects. This information includes surface properties such as transparency.

The render takes longer, but the shad- ows are improved. To use this feature, follow these steps Press the Take Settings From Maya button. Doing this will automatically copy the settingsfrom the Maya Depth Map Shadows settings. It will also automatically ll in the name for theShadow Map camera settings.

Decrease the Camera Aperture setting, and increase the Camera Resolution setting. Test therender, and adjust the settings until the desired result is achieved. Use the scroll bar at the bottom of the render view to compare this render with the previ-ous two renders Figure 9. Save the scene as. Detail shadow maps are more sensitive to changes in the Softness setting in the Shadow Map Overrides rollout.

There are also additional Samples and Accuracy settings in the Detail Shadow Maps rollout that can be used to tune the quality of the maps. You can use the Shadow Map File Name eld to set a name for saved shadow maps and then reuse the shadow maps to improve render time as long as the lights are not animated. The settings for saving shadow maps are found in the Shadows section of the Render Settings window on the Quality tab. The bottom line is when using depth map shadows, you can use a number of options to improve the quality of the shadows.

The goal is to strike a balance between render time and quality. To see a version of the scene to this point, open the scene from thedirectory on the DVD.
