Some times, we want to view different shot with different ocio config in one nuke script. But the default OCIODisplay and OCIOColorspace node will load the config file which is in nuke's root setting. So these two nodes allow you to load a config file by custom.
This two nodes are modified from OCIO offical nodes.

For Linux and Mac and other version of nuke:
You can compile the nodes yourself using the source code in the rar file. Go https://github.com/imageworks/OpenColorIO/blob/master/docs/installation.rst to see how to compile and set enviroment.
