| Do you have some examples you can link to of something you have rendered in a few seconds? Fusion has some sort of simpler preview, my guess is that its some closed form lighting solver and in certain contexts it can look ok but for photorealism of a scene, its nowhere close. I see a decent number of suggestions that people have really fast renders but I'm suspicious that we are talking about very different things. Here is what I am typically rendering: -Full screen on a 15" retina MBP -Ray Traced -In additional to the product, whole rooms/scenes that contextualize including 3D textured woods, books with Decals that are wrapped, elements of various opacity/transmissiveness, objects with some luminance, etc. - Some objects with very high numbers of points (there is a technical name I'm forgetting), but essentially, circles render with enough polygons to not appear as a collection of lots of small/slightly noticeable line segments |
