Hey Orbo,
I will need to do a quick hot fix for this, but with library overrides all the custom properties need to have the “make overrideable” enabled in the original rig file.
When I get a chance I will fix all the download files but if you need to quickly get it up and running – here is a script for you.
Copy and paste this code into the text editor, select one rig at a time, then run it (Alt P)
Then save the file.
import bpy
rig = bpy.context.active_object
bones = [bone for bone in rig.pose.bones]
for bone in bones:
for key in sorted(bone.keys()):
if key not in '_RNA_UI':
bone.property_overridable_library_set(f'["{key}"]', True)
It will only work on the active object, if that object is an armature.
Yes I’ll do a proper update to the download files, but that’s probably not going to be today.
