In-Depth Information
The description of the node is as follows:
Flaps control the number of sides of the bokeh shape
Angle rotates the bokeh shape
Rounding reduces the sharpness at the corners of the sides
Catadioptric creates and increases empty pixels from inside the bokeh
shape
Lens Shift adds a chromatic aberration effect to the shape, splitting the
shape with color offsets
Output nodes
Output nodes should be used to fetch data from the compositor and to view it in the
UV / Image Editor or save it as an image or image sequence. Different output nodes
are shown in following screenshot:
The Composite node
The Composite node connects the output of a composite flow to the renderer. Con-
necting a node to the Composite node will output the result till the connected node,
when rendered. Leaving the Composite node unconnected will output a blank im-
age. Having multiple composite nodes might give unpredictable results.
The Image , Alpha , and Z input sockets store the corresponding connected results
into the respective image channels. The Z input can be used only if the EXR format
is chosen as the output format. This node can also be used to route the output to the
UV / Image Editor.
The Viewer node
The Viewer node is a handy tool to inspect the compositing flow. Using this node,
the output can be tunneled to backdrop of the Node Editor or the UV / Image Editor.
