No use to record it. It just goes like this. I start a render and it takes about a minute after parcing the scene before displacement is beginning to run and after about another minute or so the render starts with GI and first pixels. I render the image to a few passes or more. Make a few changes or a new camera and start again, click render and CR shows it started parcing the scene but then stalls, need to force quit (shows C4D is not responding). Then I restart and things are back to normal.
I can't start two scenes after one another without restarting, sometimes just C4D other times the system. I can test again next week with smaller files. But for now I need to get the project done before the end of the week.
Attachement is an example of what I am working on right now. Lots of Chaos Scatters. (The grass in the foreground, the trees, plants everything really). The masonry is displaced in two different depths. Very sensitive on the direction of normals btw. Had to manually adjust a lot of geometry to get it to work. The sky is great, I hardly ever use hdri's anymore although in this particular image the clouds look a bit off because of the wide angle at 16 mm.
