#AutoWrite
Semi-automatic output paths for Write nodes in The Foundry's Nuke. ##The gist:
Create output paths by parsing the Nuke script name and path.
Most of the information needed for the output of a Nuke script is contained in it's name. We can reduce manual name changing on behalf of the artists and simultaneously increase consistency by creating a Write node that creates (and updates) it's own output path by parsing the script's name.
##The details:
Most projects at a facility will use a standardized file hierarchy, which means that a Nuke script's name and path on the filesystem will often contain all the information needed to define the output destination for it's render. As an example, here is a path from one of my comp scripts:
/Volumes/PICO/show/testproj/abc/abc123/nuke/abc123_comp_v01.nk
From this path, we can see that I have a project called "testproj" that has a sequence with an abbreviation "abc" and that there is a shot called "abc123" in that sequence. I am working on composite version #1 on that shot.
What I do to create an AutoWrite is add a tab to the Write node where I break down these path elements in four knobs: project root, sequence name (or abbreviation), shot name and script name. These knobs are then re-assembled to create the AutoWrite's output path.
Since each facility creates their own file structure, I have set it up for my own structure and I leave it to you to parse your own paths for your facility.
Because this node creates paths that don't yet exist on the filesystem, you'll want to implement the beforeRender callback listed in the Nuke manual (page 575 for Nuke 6.1v2.) That way your auto-generated output paths get auto-created on render and life stays groovy.
