Blender had once upon a time such IKA systems i miss. I Used the IKA to animate pneumatic pump.
The way i did it in the version 1.80a was to:
- add two sticks (big, small).
- add an ika in both sticks
- parenting the sticks to the ikas.
- parenting the ika to each other ika.
The Armatures-Objects looks like a much more complex feature than i need.
Any idea how to construct this is a new blender version?
