There was a breakdown of one of their last projects where they showed the compositing for each shot - base render, 4/5 layers and a few color correct nodes. I cant find it right now but each shots string was about 15 nodes long, and their big thing was being able to copy every shot into the same fusion file for consistency.
i assume thats an other one from blur.
This is correct, yes
