In unity and by extension UDON. Object’s transforms are not just 3dimensional. This goes for their rotation.

It’s actually 4 dimensions of rotation. X, Y, Z and W.
W here is the quaternion.
You usually do not need to think of this when using the animator component.
But if you are gonna use code to rotate an object you will have to consider it’s quaternion too. Which is a weird inside out rotation m. Google quaternion to see what I mean.
