Took a quick look and it seems you have to enable fk in controls to get the hips to move the arms. There are some ik/fk switches but I am not sure how functional they are, it would take a lot of time to dissect the rig itself. Make sure you change the display to show full hierarchy in OM, it will be easier to troubleshoot
Here is a nice setup I spent too much time on - Lorenz attractor!
There is some fancy math inside and controls are available. If you want more performance turn the capsule into spline one without geometry and vertex color generation
210_Lorenz.c4d
You can use destination spline in mospline (just convert the original and place as target). This way you can load the target spline into timeline and bake all the keys. From there you can create your loop
Pm request - rolling sphere! : )
Important note about this is that nodes (at the moment) require keyframed values since system needs to have access to previous values in order for proper rotations.
81_Roll_it.c4d
An easy way is to remesh the booled mesh with cylinders generated by surface blue distribution. Check the scene : )
Use the distribution in capsule to fine tune and determine count
Pickleball.c4d
Few ways to do it. Pure modeling (make a section, maybe 1/8 of sphere and copy/clone) or use a cloner to make 40 cylinders and use that with boole or volumes.
Bouncing ray setup. It fires a spline in Z direction from referenced object and bounces from detected geometry set number of times
