Vito (the guy behind Con-Fusion) is an entertaining presenter with a deep understanding of shading and lighting with Fusion's 3d system. I'm a fairly accomplished Fusion compositor, but he manages to teach me something new with almost every lesson.
I recommend supporting him on Patreon:
https://www.patreon.com/VitoFor $10/month, you'll get access to his video tutorials, downloadable comp files and assets, and he'll offer support.
