Render passes
Passes or AOVs (arbitrary output variables) are intermediate computational results
that are shown when rendering a layer. All render passes are buffered out when ren-
dering a render layer and written as separate data. These passes can be utilized
in compositing to rebuild the beauty of the render layer and also allow us to tweak
individual shader/light contributions. The following screenshot shows the Blender in-
ternal render engine's

panel:
Every render layer in Blender, by default, is equipped with these render passes, but
the content in the render passes is based on the data available to the render layer.
However, the pass definition and the type of content it stores doesn't vary. All passes
that have a camera icon beside them can be excluded from the combined pass data
by clicking on the camera icon. This provides another level of control over the con-
tent of the combined pass.
Each passes' significance and content
The following screenshot shows outputs of different render passes available, by de-
fault, in Blender's internal render engine. Their significance is explained as follows:
