Finger - rigging - Action constraint

Support Animation and Rigging

Hi there, Namaste :pray:

I am using Blender 2.92, and now rigging my characters myself, starting from a single bone, following the wonderful tutorials of reverent tutor, Mr.@NathanVegdahl. I faced a problem in finger rigging. I made an action for bending the fingers from frame one to 22, and saved the action with fake user. If I’m making an action constraint with the saved actions in the fingers which are assigned with Euler rotation ‘YZX’ as explained in the tutorial which was actually working well in previous versions of blender, is not working in this version 2.92. If I’m setting the rotation of the bones to quaternion, it works!

I don’t know whether something else is to be done, but this is a problem(?) I faced while rigging my characters in Blender 2.92. (I changed the rotation to quaternion as of now, and it is working)

I shall be thankful if someone explains the reason for the same or the possible error made by me.

Thankyou.

Euler rotation is easy to understand (rotate in every axis) but there is a problem when crossing axis.
Quaternion don’t have this problem, but “the numbers” irritate some people.

Thank you for the response.

This may not be a bug, but I do remember that the action constraints worked on the finger bones with Euler rotation set on it, but it was not working in 2.92 unless the rotation of bones is set to Quaternion.
