Rendering Performance and Quality

A render is not finished when the ‘kernel → maxsamples’ are reached. It is finished when the Viewport image quality is free of noise and all details have been rendered to a fine level. For some simple scenes, this will be after 500 samples. For some complex scenes it may take 10,000 samples.

Tips to increase render speed (by increasing sample/sec or reducing the samples required to finish the render):

IMPORTANT: Remember to adjust ‘kernel → ray epsilon’ for each scene. The ‘ray epsilon’ will be smallest for close-up renders and increase as the camera moves further away from the subject.
