how to Rig / Animate a Multi Lobe Camshaft Hi im Trying to animate multiple Cam Lobes on a single shaft
Like So
and each Lobe is at a different interval to each other which is where I have drawn a blank.
and each Lobe should drive their own individual Valve
Does anyone have a super Solid Solution to this
Here is the File if you need the Physical Camshaft and Valve Setup to help me with my rigging problems
Have you considered using  Shrinkwrap constraints?
Here. the valve-rod is parented to an Empty, which is constrained to be projected onto the surface of the cam, down its own Y axis..

If the slight penetration is a bother, maybe that could be tweaked out by keyframing or driving the constraint's offset, or influence? Or by having a hidden, slightly reshaped cam, to displace the Empty,avoiding intermittent intersection with the rod.
Example settings.. the Empty is constrained to the Cam, projected.
