This came up in a private conversation but I felt some of it merited a public post.
Final Quality Renderworks is NOT what I would consider Final. It's name is a holdover from a previous rendering engine and leads a lot of users to think that if they slap that FQRW button, they'll get the best rendering possible, I hope to get this renamed soon. This perception can also be colored by how nice OpenGL can be made to look these days, as it has advanced considerably since 2010.
Below is a brief example of what I mean:
For many, this file in OpenGL, which renders in seconds if not instantly, is perfectly fine and can be used in a presentation, but the Final Quality Renderworks example in the middle seems incomplete by comparison, even though it took nearly half an hour to render.
The example on the right on the other hand took around the same amount of time to render, but looks much better than the middle example. The example on the right is a slightly modified version of the Realistic Interior Final Renderworks style. The ONLY thing changes between these three scenes was the rendering mode used. no textures, lights or geometry were altered.
Our series on rendering covers the basics of this, and I highly recommend taking a look at if you haven't before:
Another series from Daniel Jansenson covers them as well:
