They are not clones, they are stage lighting fixtures, each fixture is several nested groups, with a light object nested in the head object (which rotates on the X axis), which is then nested in the yoke (which rotates on the Z axis), which is then nested in a stationary base.
The goal is to have each group of fixtures (between 4 and 8 usually) fanning out slightly, with about 30° of rotation from one fixture to the next, all on the yoke (Z axis).
So I want to grab 5x individual Yoke objects, and have some fancy way of telling them to spread out their rotations.
Please forgive the repeated explanations, I just want to be clear. Also, I hope I got the nomenclature right, I’m used to Architectural or Manufacturing 3D drawing packages.
