I got “Unable to acquire V-Ray For Rhinoceros GUI Licence”. I work on an important project and now I can’t work with V-Ray. Is it because of internet? I use trial and still have 6 days left. I have no internet connection and I will not have next 4 weeks. Is it necessary to have it?
You could checkout the license to be able to use it without internet, but you have to do this through the Online License Server (OLS). To use the OLS you will need internet.
Internet connectivity is on the system requirements list. You can use the license offline, by borrowing it, but for that you habe to log in at least once.
