Hello !
I would like to create a skeleton like bone_parent → bone so I tried to use “Add Leaf Joint” on the control_01 guide but doesn’t seems to do anything.
Here is the result :
The first guide has the feature checked
The second one is with only one bone
I can create a new issue in github if needed !
My current workaround : create two guides, one with “joint”, the other with “joint” and “is Leaf Joint”
@remicc
Turn off “Force uniform scale” in the main settings of the guide root.
leaf joints are designed to support non uniform scale, so are not needed when uniform scale is forced 
Okay ! That wasn’t intuitive, maybe the tool tip should contain “Needs Force uniform scale unchecked in the guide root setting” 
Also, even if I had some custom joint names in the guide :
It doesn’t care of the second name, and add leaf_ in the first name… It should be nice to have this behavior by default but take joint names if they exists so the leaf_ would be customizable.
But that doesn’t fit with my needs, because I wanted the control to constrain only the leaf bone, so anyway my request isn’t very important😊
Thanks for your answer and your help, as always !
