OpenColorIO COP2 nodes for Houdini as Nuke counterparts 
An unofficial HDK plugin to bring Nukes well known OCIO nodes to Houdinis compositing network.

Hi guys,

this is my first post on the mailing list. I'm a Technical Direction Student from Filmakademie in Germany
and i created an OCIO plugin for Houdinis compositing network that aims to bring Nukes OCIO nodes to Houdini.
Please feel free to have a look ;)

OpenColorIO COP2 nodes? 

As an integral part of VFX and Animation pipelines, it makes sense for Houdini to support OCIO. 
A possible use case for example could be, to grade backdrops when rendering.


Here is a little introduction video 

And some images: 

  • Tab Menu
  • OCIOCDLTransform: Applies an ASC CDL (American Society of Cinematographers Color Decision List) grade based on the OpenColorIO Library
  • OCIOColorspace: Apply a color transformation based on a .ocio file. Ocio files are yaml based and describe the complete available colorenvironment. The color environment in turn usualy consists of a dozen Lut files which describe transformations to/from the reference color space to the target space.
  • OCIOFileTransform: Accepts a path to a specific color lut file and does a color transformation based on it.
  • OCIOLogConvert: Do a color transformation from Lin to Log, or the other way round, based on the Lin and Log roles of the given .ocio config file.

Plugin Status 
Please note that the plugin is currently in alpha status. There are still bugs here and there but i guess it's best to release it now, so maybe it will get some true battle testing. 
Should you find bugs, please feel free to submit them on the github issue tracker. 
Also please feel free to fork or clone the repo and build the plugin for your platform. I currently only supply precompiled binaries for H13 for windows, built with msvc11. 
(I want to supply Linux binaries as well, since i know about its importance in the Houdini community, as soon as i have a Linux build setup up and running). 

Git Repository

Download and additional information 
Additional information can be found on my website. 
Download the precompiled binaries here (H13, Win, MSVC11) 
The download contains example images and scenes. 

I hope the plugin is of use to somebody Wink
