I have a cylinder, with a child piston coming off it. I made the piston by following this tutorial. The piston is stuck to the cylinder by making one of the "bearings" at the end of the cylinder into a child.
When I move the cylinder around in edit mode, the piston moves with it, which is what I want to happen.
I am trying to rig some bones up for this, and I have put a bone and set the cylinders parent to be the bone. When I move the bone in pose mode, the cylinder moves, but the piston does not. I rigged the cylinder to the bone by selecting "Armiture Deform -> With automatic weights". I tried to set it as a bone, but it teleports the cylinder somewhere else. No idea what is up with that.
Why does the piston not move with the cylinder when I am moving the bone? How can I make the piston move with the bone in pose mode?
