We use the term Vray to indicate that a rendering is photorealistic but you can pretty much achieve the same quality with all rendering engines (Maxwell, Mental Ray, Iray, Artlantis, Octane). Speed of rendering is a good selling point, but it doesn't have any value when you present an unrealistic cartoonisch looking interior scene. 10 years ago you might have gotten away with that and some of you still have clients who except that quality, but nowadays everyone is already accustomed to the "vray" quality. I gave an example on how real estate agency, who typically are the last in line when it comes to technology, have vray quality images to present their unbuilt work. It's everywhere. Drive by a construction site and you will see a vray quality rendering on the billboard. So I have no idea in which market you can get away with Lumion interior stills. And If you say that Lumion is primarily for exterior scene, would be a strange argument because most architectural images produces are interior renderings. after seeing the faces which is pretty straight forward, clients want to see how the building works from the inside. If anything, Lumion is suite better for landscape architects, with their beautiful realist looking trees, grass and water and where reflection and GI doesn't play a role. .
So, my suggestion is to either build raytrace in Lumion or have the ability to export a lumion scene to a software that has raytracing. If I have to built to different scene in two different software packages defeats the purpose of Lumion. And besides, raytracing is the most inexpensive and easiest feature to built in. Apart from the common rendering engines, cad/BIM packages have raytracing in them as well, while it's not even a main feature. Let the user decide whether he wants cartoonish looking images in a zip of time or a high quality photorealistic rendering but the trade off of longer rendering times.
