Output
File Output allows you to t ake a “snapshot” of a
rendering before some or all of the other Render
Effects are applied, depending on the placement
of File Output in t he Render Effects stack. You
can save different channels such as Luminance,
Depth, or Alpha to a separate file while rendering
an animation.
You can also use File Output to convert an RGB
image into a different channel and send that image
channel back into the Render Effects stack. The
rest of the effects can then b e applied to that
channel.
