I would like to align 10 bones,called DEF_arm bones,to existing bones,called MCH_armSpline bones but I don't know how to do it. I tried selecting all the bones together and a bone at a time and then I did snap/selection to cursor
,but it didn't work. Also I don't understand why, in edit mode, ALL the bones are perfectly aligned together, but not in pose mode. I attached a short video to show you,thanks.
NB : I know how to put bones into the position the were originally in, aka the "rest position" ; I do Alt R ; Alt+G ; Alt+S" and it worked,but,as you can see from this picture, the last bones that I aligned aren't on the same position with the others.:
And if you look at this pic you will see that on the tutorial that I'm following all the bones are perfectly aligned also in pose mode:
