12:05:39.028 [ERR] [vrdx::ColorManager::setOCIOLook] -1: OCIO configuration not loaded
It looks like Blender is using a newer OCIO version. Your Vantage log probably contains this in one of the error lines:
“config.ocio’ is version 2.5. This version of the OpenColorIO library (2.4.2) is not able to load that config version.”
We will have to upgrade the OCIO library shipped with Vantage in one of our next updates, maybe in 3.4.1.
