Python Scripting : autoComper - Nuke (Free Script)

 

This Python-Script for Nuke written by Jan Oberhauser allows to make a basic-comp on the push of a button. It does not matter if it is a MultiChannel-EXR, One-Channel-EXR or any other File with just one-channel like TGA, TIF, JPEG, ...
The Script starts to look for the Channel-Names and if the file just has the 'rgba'-Channel it checks the file-names. Then it orders the Nodes, comps them with the nodes defined and also creates additional nodes. 
Example: It looks for the depth-Channel, then adds a Grade-Node, copies the channel into the depth-Channel of the main-tree and adds a zBlur-Node afterwards.
This is just a Basic-Setup. But it can get easily get changed and expended much more just for every need with changing a few variables. For example different setups for background. creatures, effects, ....

Python Scripting : Nuke PSD Layer Shuffle

A modified PSD Reader plugin for Nuke by Nathan Dunsworth which outputs the PSD files layer order into Nuke 5.2 meta data.

Python scripts can query the Read nodes meta data and perform operations such as shuffling the PSD files layers into RGB and re-merging them back together, or shuffle the layers into RGB and create 3D Cards separated by layer order.

NUKE's Precomp node with Frank Rueter

NUKE's Precomp node with Frank Rueter from Hieronymus Foundry on Vimeo.

This tutorial is by Frank Rueter. Visit his website for more : http://www.ohufx.com/

This shows how to use the Precomp node in a workflow that enables the artist to use external NUKE scripts as an input to their main comps. This helps to keep the node graph tidy, but also opens up the option to work with centralised NUKE scripts as inputs without having to pre-rendering them.

Such a workflow is invaluable for shows that need to share the same NUKE script as a background. For example, only one NUKE script needs to be changed to update all main comps that depend on it across multiple shots.

This tutorial shows you how to set up such a script dependency and how to work between the precomp and the "receiving" comp.
