Aleksey Voznesenski Covers How Important Up Vectors are for Rigging and Animation.
If you want an easier time with the animation process, the answer is to create a rig with controls. If you want an easier time with building simple rigs, you need to have an understanding of Up Vectors and how applications make use of them.
Check out Ace5 Studio’s latest tutorial that covers what Up Vectors are in Cinema 4D and how you can use them in a variety of places when you are creating rigs for your work. Vectors become really important when working with constraints. Aleksey covers techniques that you will find useful in many places, like building a forearm twist for a character, rigging eyes, and more.
