Problem summary When setting up a custom OCIO configuration through the %OCIO % environment variable, Nuke will use the the config.ocio for its "default LUT settings" as expected.
NukeStudio and Hiero do not use the %OCIO% environment variable location and will use the default .nuke/uistate.ini location for its "Default Color Config" instead.
As the environment variable is specifically set to a location, NukeStudio/Hiero should use the given config.ocio instead.
Customer reported version nuke.10.5v7
Customer reported platform fedora
Steps to reproduce
1) Download the attached CustomOCIO.zip and extract to a temporary location.
2) Set the Environment Variable to the config.ocio file within the downloaded folder path.
For Windows, copy the following into Windows command prompt: ( Replace the folder path to your downloaded file directory )
3) Launch Nuke. Open Project Settings ( S ) and navigate to the Color tab.
4) Set color management to OCIO.
Values of default LUT settings will refer to roles in OCIO: ( Custom OCIO is set to use 'raw' for all option fields )
5) Launch NukeStudio\Hiero, Open edit -> Preferences via the toolbar and navigate to the Color Management tab.
Result: The values in Default Color Transforms do not use the %OCIO% environment variable custom settings and instead keep using .nuke/uistate.ini:
NukeStudio Preferences Window:
Default Colorspace values within .nuke/uistate.ini:
Workaround Unknown, setting up the custom OCIO config through the .nuke/uistate.ini file unfortunately do not work.

This bug has been reproduced in: NukeStudio11.1v3 - Windows 7 - Mac10.12 - CentOS6.9 NukeStudio11.1v1 - Windows 7 - Mac10.12 - CentOS6.9 NukeStudio11.0v4 - Windows 7 NukeStudio11.0v1 - Windows 7 - Mac10.12 - CentOS6.9 NukeStudio10.5v7 - Windows 7 NukeStudio10.5v1 - Windows 7 - Mac10.12 - CentOS6.9 NukeStudio10.0v6 - Windows 7 NukeStudio10.0v1 - Windows 7 - Mac10.12 - CentOS6.9 NukeStudio9.0v9 - Windows 7 NukeStudio9.0v1 - Windows 7 - Mac10.12 - CentOS6.9
Earliest version tested - This issue appears to be in all versions of the product Expected behaviour NukeStudio/Hiero "Default Color Transforms" should use the OCIO environment variable configuration
Actual behaviour NukeStudio/Hiero uses the .nuke/uistate.ini file, which is confusing for user's setting up custom OCIO configuration for both Nuke & NukeStudio
