Developers of Allplan 2015 made own(imho) real-time renderer(path-tracing closer), moved from c4d(i don't think that is IR renderer in c4d and somehow it was ported)
There is interesting, will VW moved to c4d r16 with new reflectance model of material, will be nice feature for engineers or metal designers, I remember Jim's chrome analysis
Or made something anything
I touch only vis and view-port interactive sides of VW
