Blender driver and expression skill. Use it to:
- Add drivers to any animatable property (
add_driver) with typesSCRIPTED,AVERAGE,SUM,MIN,MAX. - Edit driver expressions without replacing the whole driver
(
set_driver_expression). - Manage driver variables — add (
add_driver_variable) and remove (remove_driver_variable) the named variables a scripted expression can reference. - Inspect all drivers on an object or scene-wide (
list_drivers). - Evaluate the current driven value at the scene frame
(
evaluate_driver_expression). - Remove drivers cleanly (
remove_driver).
This skill maps roughly to Maya's Expression Editor and Set Driven Key
workflow. Use blender-animation for plain keyframes and blender-rigging for
bone/constraint setups.
