6.4 Rendering• Stop Frame: Sets the end frame of the sequence to be rendered.• Frame Step: Skips a predefined amount of frames between rendered frames,e.g.: Frame Step 3, Start 0 would result in rendering frames 0, 3, 6, 9...• Frames Per Second: Sets the frame rate for the image sequence.» Cluster:• Enable Cluster: Enables the cluster.• Hostname: Defines the clustering slaves. Hostnames as well as IPs can beused to access the slaves.» General Settings» Antialiasing: The Antialiasing settings control the number of samples takenduring stillframe antialiasing. These are the primary controls that influence thequality of the rendered image.• Image Samples: Sets the number of samples taken during stillframe antialiasing.Higher values produce a cleaner result while lower values reducethe render time. A value of 128 is recommended as starting point in generalbut may be too low for interieur scenes with full global illumination.• Adaptive Sampling: Adaptive sampling allows the raytracer to skip regionsthat are already smooth and focus the processing power on regions thatare still noisy. The various quality settings control a threshold for a regionto be considered as smooth. Setting the control to “Highest Quality” disablesadaptive antialiasing and always samples each pixel with the numberof image samples specified. While this gives the highest render quality itmay waste processing power on regions that are already smooth.· Preview Quality: Sets the sampling quality to a very low level, resultingin preview render quality and very short render times.· Low Quality: Sets the sampling quality to low level, resulting in averagerender quality and short render times.· Medium Quality: Sets the sampling quality to medium level, resulting ingood render quality and medium render times.161
