Hello!
Had a question in the "help" area and since nobody said a word i assume this feature is not in Corona yet.
When you in interactive mode and resize the VFB, the whole scene restarting and image get resized to a new size of the VFB which is annoyng as hell. In VRay there is an option to turn off "Fit resolution to VFB".
Would be awesome to have this feature in Corona, guys. Please, add it!
