“I’m pretty sure rotations can sense fear…”

[Adam Janz]

LOL… this was best overview of Quaternions vs Eulers ever. I still don’t understand how Quats work, but all I know is DEFINITELY avoid on the root bone if you’re making game animations with root motion. Trying to make a barrel-roll or similar animation is so much easier when you have degrees… 🙂

Don’t give up on quaternions.  You will get the hang of them, remember it’s the fear they sense.

Always use Euler for 1 or 2 axis of rotations.  But if you need 3 axes not being afraid of quaternions will get you to the end goal with less headaches.

A barrel roll in Euler will not be easy depending on the rotation order and the starting direction.

I personally use Euler on the IK hands and feet and root, but I’m prepared to switch to quaterion if/when I run into trouble.

You will find your own personal preference too.

Hope that makes sense.

(Other programs don’t let you switch between Euler and Quaterions at all – thank you Blender)

Thank you, Wayne! That’s cool that Blender is so flexible in that way… 🙂
