Possibly, though not guaranteed - there is the overall .vrscene specification, of which certain things use a subset of the overall spec, e.g. writing to .vrscene from Enscape uses only a subset of everything that a .vrscene can contain (because only a subset of things that V-Ray does can be set up in Enscape, so certain aspects of what can be in a .vrscene simply cannot be set up in Enscape and so can't be exported). This means that trying to render a Corona written .vrscene via Chaos Cloud Rendering is far from guaranteed to give a result comparable to your Corona render, since it is tailored to what Vantage expects, not to everything that V-Ray would write to a .vrscene when it is being used for Cloud Rendering. It's certainly not an intended or supported use of a .vrscene from Corona.
