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
236_Bouncing_Ray.c4d
I understand and pay it too each 3 months, it is way less than what people spend daily on gum, coffee, cigarettes or whatnot : )
Seems to be very little in terms of expense for free stuff, help that can be received and vast knowledge base, at least it seems like that to me.
Hi Marijke
Not sure why are you tasked to use Pyro, I would say it is not right tool for the job, Are you looking to recreate the wind tunnel effect mostly or the whole thing?
Either way, MoGraph or Nodes would be way better for that
