Is there a way to have rigify set the default IK Parent for the hands to, for example, the Chest instead of the root?
I’m currently adding things to the metarig as I go, it is not all planned in advance so I constantly add or change a few things here and there and hit regenerate but that makes the IK Parent forget what I set and have to do all that work again everytime.
Is there a way to set it at metarig level?
Yeah I i’m setting it there but if I hit regenerate again, it will go back to the default. For example, I’m setting the Hands to “none” but when I regenerate the rig it goes back to “root” it doesn’t remember what I set…
That is expected, because you are regenerating a new rig. use the rigify rig to make the changes.
What are the changes you have made?
There could be an option for changing it in the script? But i am not familiar with that.
I thought there was a standard way, seems like a trivial thing to do. It should be in the Rigify settings the initial parent of the IK control points…
I wanted a quick “push this button” type of solution, I could invest time in reading the python script and do changes but this is not a priority for me right now so I will just leave it as an unsolved mistery for the X Files…
This is not a mystery that information is stored in the rig controls when you are deleting the rig controls and generating a new set you are deleting that information.
Hey, I figured it out:
In your Blender folder for example - Program Files\Blender Foundation\Blender 3.6\3.6\scripts\addons\rigify\rigs\limbs
find - limb_rigs.py
Just in case save a copy of it.
In the python file named limb_rigs.py, around line 442 find this part:
self.register_switch_parents(pbuilder)
pbuilder.build_child(
self, ctrl.ik, prop_bone=master, select_parent='root',
prop_id='IK_parent', prop_name='IK Parent', controls=controls,
)
Change it to this (pay attention to the paragraph order):
self.register_switch_parents(pbuilder)
select_parent = 'chest' if 'hand' in ctrl.ik else 'root'
pbuilder.build_child(
self, ctrl.ik, prop_bone=master, select_parent=select_parent,
prop_id='IK_parent', prop_name='IK Parent', controls=controls,
)
Save the modified limb_rigs.py
Open Blender, and try a rigify rig, for example a Human (Meta-Rig)
