I figured, but paying for premium was still worth it as they started almost immediately. The business didn't use those 25 nodes at same time despite showing no waiting list anymore.
Saved me quite a deadline.
Will try to measure the economy in some spare time to see what the average start time is.
The online managing, and auto download into my folders...invaluable saver of mental sanity.
So much better than with Vray, I was always pissed it tried to "please change this, and that, x999" accomodate my settings and workflow to some strange only passable way. Great thing with Corona,
there are no settings so Rebus can't have those problems. It's still strangely nit-picky about all sorts of 3dsMax settings but I guess it's to avoid issues on nodes.
