Custom outputs can also be added by clicking the '+' button at the bottom of the lists.Įach output has its own settings which appear below the lists when an item is selected in the list of outputs. You can add other outputs by selecting from the list of presets in the list on the left and clicking the arrow button between the lists. The default output of the Final pass is, as you might expect, rgba, the color (Ci) and alpha (a) channels of a typical image. The Displays tab shows the outputs for the selected pass. When you first open the AOV tab you are presented with the outputs for the default render pass. If you do not know what file types you might need, leave it at default.
#RENDERMAN IT EXPORT DRIVER#
You must use a file format in the Display Driver that will hold these channels, we recommend leaving the default of OpenEXR nearly 100% of the time. If you want a smaller list or maybe single file output with these channels, be sure and have a Display Driver selected on the right when you add the Channels using the arrow-to-list button on the bottom left of the Channels box. This will auto-create a new display driver with the same name to be rendered.

The quick and easy explanation: Choose the Channels on the left you wish to render by double clicking them.

#RENDERMAN IT EXPORT DRIVERS#
This UI allows you to create Display Channels (AOV selections and LPE sources) and Display Drivers as their destination file (TIFF, OpenEXR, etc). Passes can each have their own camera and render settings, which act as overrides of global render settings. It is also possible to create additional "passes", which are more akin to Maya's render layers (which are also supported).

These are also known as Arbitrary Output Variables (AOVs). The primary use of the passes tab is to create additional outputs for your render.
