I model everything in VW, after that I send it to C4D. In C4D I do all the textures and lighting.
I prefer C4D for that, in my opinion its is easier to handle lighting and texures there (C4D doesnt import the texture, but is has a 'connection' to the image file, so much better!).
Besides that: allot of time I tweak the geometry of the scene a bit in C4D, or reuse an exicting scene.
The tweaking is really easy because you can drag 'points' in C4D.
So making a room twice as big, or a table 10cm shorter: done in 2 mins
Anonther reason to do everything in C4D are the different export options and possibility to export selection filters for PS.
I almost always use the psychical render. The last render is a combination of the sketch render and psychical render, and put together in PS.
