Hi there !
I used Octane for a few years and I'm now using Corona (that is absolutely amazing, definitely the best when it comes to photorealism and interior render).
In Octane there is an option that allow you to stick the camera view in the render window, then move around in the viewport without restarting the render.
Basically you get in the camera view (with all your active settings), you block the camera view in the render window, then you get out from the camera view and you can move around in the viewport.
Is there a way to do this in Corona render ?
I'm not sure I'm being totally clear... ;)
Thanks !
