These are the primary controls that influence the qualityof the rendered image.» 0Image Samples: Sets the number of samples taken during stillframe antialiasing.0 Higher values produce a cleaner result while lower values reduce the render time.0 A value of 128 is recommended as starting point in general but may be too low for0 interieur scenes with full global illumination.» Adaptive Sampling: Adaptive sampling allows the raytracer to skip regions that0 are already smooth and focus the processing power on regions that are still noisy.0 The various quality settings control a threshold for a region to be considered as0 smooth. Setting the control to “Off” disables adaptive antialiasing and always sam-0 ples each pixel with the number of image samples specified. While this gives the0 highest render quality it may waste processing power on regions that are already0 smooth.» 0Preview Quality: Sets the sampling quality to a very low level, resulting in preview0 render quality and very short render times.» 0Low Quality: Sets the sampling quality to low level, resulting in average render0 quality and short render times.» 0Medium Quality: Sets the sampling quality to medium level, resulting in good ren0 der quality and medium render times.» 0High Quality: Sets the sampling quality to high quality level.» 0Ultra High Quality: Sets sampling quality to a production quality level.» 0Use Clamping: Sometimes sampling may result in single very bright pixels that are0 hard to antialiase. There are two options to get rid of these samples:» Tracing many more image samples: Clamping the image values to a specifiedmaximum value. Be aware that the results may look dull if the clamping value is284
