The Split Viewer node
The
Split Viewer
node allows you to inspect two images or two parts of the compos-
iting flow. Clicking on
X
will display a side-by-side comparison and clicking on
Y
will
display a top-down comparison. The image connected to the top socket is displayed
either on the right or on top of the window. The slider provides an adjustment to the
location of the split between the two sockets in the viewer.
The File Output node
The
File Output
node can simulate
AOVs
(
arbitrary output values
) from the com-
positing flow, similar to rendering passes from a render layer. Connecting this node
to any other node will write an image from the calculations done till the connected
node.
The Levels node
Connecting the
Levels
node to an image can output the value of a selected com-
ponent of the image. Combined RGB, Red, Green, Blue, or Luminance channels can
be read from the connected image. It can output mean/average values or a standard
deviation, which measures the diversity of values.
