A quick and easy Bokeh Shape input. Simply plug it into your favorite defocus Node, (including Convolve) and away you go.

Unzip bokehSelecta.zip under your local .nuke folder (please keep the folder structure as is, must be .nuke/python/ to work).
Regardless of OS, the script will place the bokeh asset in the folder your Nuke Script is saved to, allowing it to work with network rendering.
