As mentioned in this post Live Link problem - Vantage :: Issues - Chaos Forum we will be releasing a new version of Vantage next week and the issue should be fixed. I would suggest that you downgrade V-Ray to the previous version. Apologies for the inconvenience.
I have updated to the recent vantage release 2.2.0 and trying to “render animation with chaos vantage” Still getting the error message: “Chaos Vantage script command failed, try to update Vantage to the newest version” You suggested to export as vrscene but the Camera movement set in 3dsMax is not exporting and I need to render exactly this animated Camera. What is the solution? I need to deliver and don’t know how to proceed here.
Nevermind - I restarted my system and the 'render animation with chaos vantage" seems to be working now
