recently I started Blender and I want to recreate a simple rig I already did in Houdini. Unfortunately I am not able to recreate my setup so I am seeking advice on several issues.
First of all I have no idea how to add an IK chain for 3 bones. When I get the workflow correctly I have to edit my Armature in Edit Mode, then select the last bone -> Pose mode and there I can assign a Inverse Kinematics Constraint. But how does it work with three bones?
I have robot parts, so I don't need any envelope or weight. My geometry could be straight parented to a bone. How does that work in blender (does it?)
Root - Chain Goal (drives the very end of the bonechain) - Bone1 - Geometry1 - Bone2 - Geometry2 - Bone3 - Geometry3
But how am I supposed to bind a chain end to an empty/circle for animating?
For a better understanding I enclosed some images what my rig needs to do. Any help, tips or links to tutorials would be highly appreciated. All I find is basic IK or guys trying to rig biped characters in 10 seconds ..
