Firstly it’s worth mentioning this is not officially sanctioned by Animation Mentor, and their logos etc are all copyrighted (copywritten?) to Animation Mentor. Also this is a resource aggregation. So the videos presented here are owned by their respective creators. Be sure to give them thanks for making great informative content!
I am putting together a few resources that I have come across and found useful during my stay at AM. These should also be of use to non-AM students too, but the links below provide relevant information at the required pacing of the course.
They helped me. I hope they can help you too!
