Is there no other way to make the 2013 do as I want? Or do I need to try again with a higher version of sk?
with a scene of nearly 200MB, I don't see any easy way around the memory issue. Can you try installing 2016 Make version and only vray 2.0 for SU and see how it goes. I would completely uninstall vray before starting on the new install.
