Creates leaf bones at the end of all currently selected bones. Useful for ensuring compatability with other programs outside of export formats.
While editing an Armature, go to Add > Add Leaf Bones
.
Select the bones you want to add leaf bones to, and then run the operator.
Select the root bone of your armature in Edit mode.
Then run Select > Select End Bones
--this should select all the outermost bones of your model.
If you use "Ignore Non-Deforming," it should not grab IK handles if you marked them properly!
Afterward, run Add > Add Leaf Bones
. Leaf bones will automatically be placed on these end bones, and selected.
Finally, run Armature > Change Bone Layers
and select a new layer to hide the Leaf Bones while you continue working in Blender.
