There are still a lot of (noted) blanks and question marks in the list, but I’ve made some progress. I have tried to compile the responses into as comprehensive a list as I can manage. Many thanks to all of you for your responses! I must say that I didn’t realize just how many SU friendly rendering programs are out there! It’s been about six days since I posted my (perhaps overly ambitious) inquiry about the “10 best” rendering programs for SketchUp. And get hold of a demo copy/free version of Twinmotion - 2019 was offered free, and 2020 is currently 50% off so it’s a good deal for a realtime engine WITH inbuilt materials and 3d assets. It will at least give you something to base decisions on. My advice is to try a Demo of Indigo because it is available for Mac and it runs using OpenCL which Radeon cards are built around (as opposed to Cuda which is nvidia-specific).

I’ve tried CPU, CPU+GPU and GPU-only on a range of different systems including some very high end rendering farms, and the GPU-only mode is so much faster! Decent renders in 2 minutes flat and it makes rendering of fly-through animations much more acheivable. One thing I would recommend is a GPU-Based renderer. Personally I would recommend Twinmotion for basic image quality, features and price. If you want realtime rendering then Twinmotion, Enscape and Lumion If you want the most built-in features with the best SketchUp interface, then possibly Vray.


If you want fast near-realtime rendering and are prepared to accept lower image quality then may be Twilight, Podium could work as they have good SketchUp interfaces. Thea looks pretty good but I haven’t tried it. Indigo is the cheaper of the bunch (RT version) and is very fast and simple to use, however the SketchUp interface isn’t very intuitive or feature-rich. If your purpose is “photorealism” (and that means fully ray-traced with atmospherics, complex shaders and materials, and a real physics-based illumination model) then your options include: Maxwell, Vray, Thea, Indigo, Arnold, Octane, etc. There a wide range of rendering engines, which all suit different purposes.
