SCRATCH - The Foundry Nuke - bridge


As of version 9.0, SCRATCH comes with an option to create a direct link between SCRATCH and The Foundry Nuke (S2N). To make this link work properly there are a number of settings you need to enable in Nuke.

Python Installation

The script to interface between SCRATCH and Nuke is written in Python. You need the Python interpreter version 2.7 installed on your system which can be downloaded from here: https://www.python.org/downloads/release/python-2715/. During the installation, make sure that python is added to your system PATH variable.

Custom Command

The next step is to create a Custom Command in the corresponding tab in the System Settings panel in SCRATCH of the correct type.

When you select the custom command type to be Nuke, SCRATCH will try and locate the Nuke executable itself. If it can not detect it, you will need to set this manually using the Set button.

Nuke Settings - Update your Nuke Plug-in path

To allow for a seamless round-trip of media from SCRATCH to Nuke and back, you need to add a script reference for Nuke. This script reference is a folder in the SCRATCH installation:

  • Windows: c:\ProgramFiles\Assimilator\Settings\Script
  • OSX: /Library/Application Support/Assimilator/Defaults/Script

You can add this script reference in one of two ways:

Using S2Nuke

The S2Nuke interface uses the Clipboard to pass information from SCRATCH into Nuke. After clicking the Custom Command in SCRATCH, you can use the Paste function in Nuke (Ctrl+V) to create a composite in NUKE. Note that in the current version you still have to launch Nuke if it is not already running.

The pasted setup contains a Read Node with the selected shot, a Metadata node with information of your Scratch project and a Write Node with the render path into your project Media Folder (into a new sub-folder Nuke/Your-Shot-Name/ ). The write node is attached to a PostRender action which will write an xml file into you Scratch Watch Folder.

When you render the node it will automatically get loaded into the Tray of your SCRATCH project, from where you can drag/drop it into your timeline or composite.

Tip, be sure to set you timeline in Nuke to Input and not Global to get the good frame-range of the shot.
