Hi ! I've become a great fan of compositing renders with the rhino viewport's "Technical" display style.
Since Maxwell will seemingly never had toon style renders, It's a way to get the look I need for my illustrations.
But a problem arises when I want a render larger than the viewport.
Up to now, I had funky lens length changes in the resulting image ; that was until I realized I had to use the "Pick film size rectangle" tool before changing my output resolution and lock film ratio.

Not too sure why Maxwell doesn't keep the defined lens legnth, but anyway...

When comes compositing time, I realize that the render is still slightly distorted compared to the initial view.
I suppose this is due to lack of precision when picking for the "Film size rectangle".

What would be the proper workflow to get both :
-Higher resolution than screen for the render
-Super-imposable render and viewport image

?

Thanks !

You can easily render at any size you want to, simply by entering the output size you want into the camera's resolution. I'm not sure why you are using Pick Film Size Rectangle here, but I would not recommend doing so -- unless you happen to pick a rectangle perfectly centered on the viewport, you will end up rendering with (a) some lens shift, and (b) an aspect ratio which does not match the viewport.

If your render perspective does not match that of your viewport, that would ultimately be because your film aspect ratio does not match your viewport aspect ratio. So my question would be, how are you rendering the technical display at larger-than-screen resolution? Because we need to make sure that the aspect ratios (viewport & film/resolution) match.

Jeremy one can use two techniques to render the Technical viewmode larger than Screen-Size
-ViewcaptureToFile or via Print-Dialog (Bitmap-Output option). One can not use your Overlay but
instead has touse the Viewport Extends in order to make the Output match.

Interesting topic!
Yeah Olivier, NPR - options are still badly missed inside M~R - but that's something I'm afraid they will never add.
