TIP If you see aliasing that occurs mostly along horizontal lines, try increasing Blur Aspect to 1.5. This changes the shape of the blurred effect. The reverse is also true. If aliasing occurs mostly along vertical lines, try decreasing Blur Aspect to 0.5. Defocusing Defocusing is a blur based on distance. With Defocus, objects near the surface are not blurred, but objects farther away are blurred. The rays cast are spread as they leave the Raytrace material object's surface. Default=0.0. TIP Increasing the value of Defocusing can give a good distance blurring effect. Small adjustments are usually adequate. Try starting with a value less than 0.1, and increase or decrease it as necessary. Also try adjusting Reflect Falloff in Raytrace material or Attenuation in Raytrace map to get the best distance blurring effect. Defocus Aspect This is an aspect ratio that changes the shape of the defocusing. Usually you will not need to change it. Default=1.0. Raytrace Antialiaser Dialog: Multiresolution Adaptive Antialiaser Rendering menu > Raytracer Settings > Render Setup dialog > Raytracer panel > Raytracer Global Parameters rollout > Raytracer Global Parameters > Global Ray Antialiaser group > Turn on global antialiasing. > Choose Multiresolution Adaptive Antialiaser from the drop-down list. > ... button Material Editor > Type button > Material/Map Browser > Raytrace material > Raytracer Controls rollout > Raytraced Reflection and Refraction Antialiaser group (enabled only if antialiasing is globally enabled) > Choose Multiresolution Adaptive Antialiaser from the drop-down list. > ... button The Multiresolution Adaptive Antialiaser dialog changes settings for the Raytrace material and maps Multiresolution Adaptive antialiaser. You can use this dialog either globally, from the Raytracer Global Parameters rollout on page 6221, or locally, from the Raytracer Controls rollout on page 5506. When you locally change settings for an antialiaser, you don't affect the global settings for that antialiaser. 5524 | Chapter 19 Material Editor, Materials, and Maps
