There are two parts in your request.
One part is the execution of this setup, but the most important part is the logic. How would the tiles fit next to each other?
You need to be able to explain how that logic would work by making some sample manual setups and writing an overview of what you want it to do.
If you provide a scene file with some examples and write an explanation of the logic, I will give it a show and maybe make a tutorial.

...I need to be able to rotate the independent geometries while keeping the IK.

I'm not sure I understand that.

Have you watched this tutorial?
https://cineversity.maxon.net/en/tutorials/kinematic-limits-how-to-rig-robots

so, this was harder than I thought... maybe there's a simpler way but I need tome to think about it.

The general idea is to cache the RBDs (balloons) and the particles to separate Alembic files, use the particle alembic ONLY ON FRAME 1 to clone the Splines and make them Ropes and add a Connector Tag, NOT a Rope Belt.
Put the Balloon Alembics into a Connect Object and make it a cloth with Mix Animation 100%.
Make the Rope Spline Connector Tag search until the ropes find the Balloons.

Here's the final file and the RBD alembic:

requested access for your project file...

here's the latest build:

can you please create a very simple scene 3-4 balloons (Spheres) and show me what you're trying to do and show me "The strings weren‘t behaving properly within the cloner"...
thanks

Please report these to Customer Support.

You can use a Spline with 16x9 size as a child of your camera. Just move it slightly in front of the camera

You can post a link to the file and also I need to know how you want to animate it.
"the rotations be free"... I don't know what that means.

Which tutorial did you follow that shows a Protection Tag?
Here's another way using Math. No need for Protection Tags:

I'm not sure exactly what you're trying to do, but here are some references for tutorials on these types of rigs:

Unfortunately there are no tutorials yet.
I assume you want to avoid the intersection of the boxes when the spline curves.
The easiest solution for that is to add a Rigid Body Tag to the Cloner and set Follow Position and Rotation to 10. That way the Simulation will make sure the boxes don't overlap while the movement is followed.

This has been fixed in the latest C4D hotfix 2026.3.3

The Lighting and shading information will not appear in the Alpha channel.
Why don't you just use the Beauty pass in after effects as a Matte?

To do that better, first emit the particles facing the camera by using "Alignment-> forward Vector "Target" and drag the camera.
Then just set the Follow Rotation to 100.

without some sort of project file it's impossible to know what's going on... can you please simplify the project and send a link?

if something seems broken, the best way is to contact customer support.

you only want to colorize this or mix the red GI with whatever your pillar color will be?

@Dutchbird
This is something you should bring up with tech support...
