Ok, having done the rigging course I think I can articulate my issue a bit more:
Minor issue- the heel pivot point seems to be slightly behind the heel in both rigs. this might be nit picky as you can probably only see it when on eye level with the heel.
Bigger issue- I can't get the FK controls to work with the stomp rig. with the rivet one they work as I would expect (when the slider is adjusted to the right) but with stomp I couldn't figure out the problem but I noticed that the copy transform constraint on the ORG_Foot bone pointing at the MCH_Thigh bone has a driver on the influence slider (or it is a driver? it's pink) on the rivet rig but not so on the stomp rig. Same with the ORG_Shin. Trying to follow the breadcrumbs with the drivers just made my brain hurt so I think I need to do the rigging course again =)
Diving into these rigs after the rigging course was really cool, they're so clean. I'll definitely go deeper into them in the future and break stuff to see how they work in more detail. What is the ORG prefix?
Ok now I'm going to tackle the Rivet walk cycle.
Hey Auto!
Wayne is working on updated Animation Bootcamp course and will be released in first half of 2023, can't give an exact date yet but it's on the way.
In the meantime, maybe you could take a look at the Melvin run cycle course, or there is the Off-Road course that uses lots of drivers, that's animation drivers, not vehicle drivers, to help get more knowledge of using drivers and how they work.
Not sure what ORG_ is, or where you see it. Maybe Original or Organic or maybe it's missing the CYB as in CYBORG?
No? Ok! I'll stick to my day job!
You may be using an older version of the Vonnbots.
There is an updated version available, vonnbots-rigs-for-blender-animators.
Hope this helps your Blender animation journey!
Those versions of the Vonbotts were rigged with custom rigify.
You use a meta rig to show where you want the bones to be, and what you want them to be (eg - arm or a leg etc)
Then you generate the rig. The 'ORG' prefix is the original bones from that meta rig.
In regards to the other issues you are having - Rigfy has the IK and FK backwards to what I would consider 'normal'.
Just slide it to the side that says FK. (which is to the right in Rigify)
And could you show a video of the heel issue. Just make sure you are only rotating it on the X axis. The other axes will bank the foot (maybe that is what you are doing by accident?)
Adrain:
I forgot to mention autobohdi is using the newest version of the Vonnbot rigs from the upcoming yet to be released animation bootcamp course.
He and another member are rig testing for me.
