The Info Pass provides a view of the effects of the normals, UVs, and geometric data provided in the scene. The info passes are rendered one at a time. The maximum samples (Max samples) for Info passes can be adjusted without affecting the maximum samples set toward the final rendered image. Info Passes include the following:
Distributed Ray Tracing
This is an option to enable z-depth and motion blur in the render passes. If this is enabled, the motion blur and DOFThe distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. Although a lens can precisely focus at only one distance at a time, the decrease in sharpness is gradual on each side of the focused distance, so that within the DOF, the unsharpness is imperceptible under normal viewing conditions. source: wikipedia (https://en.wikipedia.org/wiki/Depth_of_field) are sampled.
Baking Group ID
Specifies which baking group should be baked. By default all objects belong to the default baking group number 1. New baking groups can be arranged making use of object layers or object layer maps similar to the way render layers work.
