Hey Chipp
I found this course on retopo in 3d Coat https://www.udemy.com/retopology/learn/v4/overview

At £15 (half price today) pounds it seemed worth a punt. I dont know when I will have time to have a go but if I learn anything useful I will share it here. The trouble with being a nurse is that I don't get much time to experiment with this software. The trouble with being 55 is I forget what I learn in between sessions;)
Best regards
Keith
