Interesting and recent statistics by RebusFarm
https://rebusfarm.net/blog/the-state-of-3d-modeling-rendering-and-post-production-tools-insights-from-the-archviz-communityA few observations:
•CPU/Coronarender at the top ! Could it be that Rebusfarm results are influenced by CPU people that benefit most from a render farm. GPU people most likely don't need a render farm.
•Cinema4D lost some, Rhino too, I think to Blender
•Sketchup lost a lot. Having been using Sketchup a lot in the past, I found Sketchup to be very slow in modelling and texturing. I think that's why it's in decline.
•ArchiCad is growing. I think because it's BIM. Great if you can combine archviz with BIM. Was not a good idea for Corona to drop Archicad.
•Revit should be listed higher being used at such a large scale, probably not a modeller for renders.
•Unreal and twin motion are growing steadily I think since they are free apps
•Lumion lost a lot. Great app but their pricing was not competitive. Don't think they will be around a few years from now.
•Vray lost a lot too. Wonder why, 3ds max is still hot. What are they rendering with ?
•1069 votes and 2% C4D users in decline , that's about 21 C4D users and about 630 3ds users in this study. Hopefully this does not represent the corona-userbase for C4D very well otherwise I can't imagine C4D being supported for much longer. Especially now Redshift is for free with C4D and Redshift has a better integration with its assets in the C4D-asset browser. For people like me on a Mac, corona render/C4D is still the best option though.
