Per the title, when I have an OCIO config set in the Display Correction, either explicitly though the OCIO dialog box or through the environment variable, the pass throws an error to the listener, "Restoring vray vfb layers failed", and no layers are restored. It seems to be related to the actual file path being stored not necessarily the Display Correction set to OCIO because if the path is blank the layers will restore just fine (obviously the path is necessary otherwise setting it to OCIO is useless though).
Further, if the OCIO path is set using the environment variable it breaks all pass restores since the OCIO path seems to be saved regardless of whether or not the Display Correction is set to OCIO.
