U.R.A. - (Universal Render Adjuster) (URA)

U.R.A. is a panel that loads in Nuke and breaks out channels that are in multi-channel renders to allow for adjustment.
Please see the Info.html under the ./docs folder for a more detailed description of how the tool works or visit the link below: https://docs.google.com/document/d/e/2PACX-1vSWkAxc4E4o1jLdx53-LHO7_MuxlQM0amnP7UsoXMmfM2N8O17OwM2e1mEkx-GsUloGBbcwzWBHm_Is/pub

The tool ships with configs for Arnold, Mantra, V-Ray and Redshift, but can be update to work with any back to beauty recipe from any render package.
Test render images are available at the link below:

To install simple extract the zip and place it in a directory that nuke loads via: nuke.pluginAddPath({PATH_TO_URA})
Install instructions included for modifying pipeline specific workflows in ./docs/install_readme.txt:
- Configs
- Custom nodes
- pipeline_custom script

A huge thank you to everyone using the tool and providing the feedback that allowed v2 to be so much better than v1.
This release brings a lot more stability and accuracy to the workflow, while still feeling familiar to long time users of the toolset.

Keep that feedback coming.
