Me too, that one is a really great thing, but most probably Corona's version of it should be done by a Rich Dirt developer himself, though given some maps which were not designed to work with Corona originally but work nevertheless, it probably is possible to do on Corona's dev's side as well or at least I hope so. There was some request\discussion about R.D. earlier - a year or so earlier that is - people were getting ready to write some request letters to the r.d's dev. but I'm quite sure that wasn't accomplished or there were not enough Corona users for him to be interested - who knows. I, myself had bought it in some like 2011 or so and now my licence is only viable up to max 2012 + I've stopped using vray around that same time and thus stopped using r.d. too and didn't upgrade my license since, but I used it quite intensively until then and it surely was good while it lasted )
