Hi all -
Just a heads up if you're using the latest Cinema and Octane that scenes should use the "basic" color management set to linear for things to work normally, but note that if you send that scene to the render queue > close out of that scene > if the new.c4d file that opens uses OCIO instead of "basic" - the Octane scene in the render queue will start to have incorrect colors.
Easy fix to set the new.c4d to use basic like default, but if you're like me you might have different settings, and it took some time to find this behavior.
