Trying out C4D for about 3 months now..
Build the 'R' from 4 sculptures (we're doing a 36daysoftype sort of thing on IG)

Image took 53mins to render. FOD image too about 2 hours...and the animation (which is a behind the scenes to show how the R was build) about 10 hours (yikes!).
All on my iMac2013....

Really loved the class and your way of teaching and explaining!! Keep it up!
