Piston Rigging (Patreon)

H'okay! Here's a bunch of different piston rigging techniques! Dependency loops are one of the biggest issues when trying to set up a piston rig (you typically target each half to just point at the other half, but blender hates it when two things are dependent on each other). For that reason I like doing it with an IK chain, which maybe seems like overkill, but it's quick to set up, and incorporates into other parts of the rig really flexibly. I think these are probably the easiest ways to rig up a piston, but I'd definitely love to hear if there's a technique I don't know about!
