Hi Noseman,

As you suggested, moving away from the particle system, I tried approaching this using a "Cylinder with a Cloth tag" and a "Sweep with a Rope tag". However, I still can't quite achieve the braiding mechanism and the exact setup I need.

If I could somehow create a setup where a "Cylinder + Cloth tag" is continuously generated and extending from an Emitter, I would be able to replicate the mechanism seen in the real-world video and finally achieve the animated scenario I am dreaming of. I hope this sparks your curiosity and we can figure out a solution for this together!

(I also want to kindly remind you of this 6-year-old C4D video: https://www.youtube.com/watch?v=Z4TJp95T6ys. It seems they actually managed to build a continuously growing dynamic rope system out of an Emitter using those specific tools).

If you have the time to take a look, I have shared a Drive folder below containing the "Cylinder - Cloth tag" scene, the "Sweep - Rope tag" scene, and the real-life reference video of the machine.

Thanks again for all the help!

I have one last question, and I would be really grateful if you could take a look. Attached is my scene.

Object '1' (Emitter/Tracer) is interpenetrating itself instead of coiling/piling up like Object '2' (Sweep). I tried Rope/Simulation tags on the objects/splines, but with no success.

Any idea what I'm missing? Thanks again!

Hi Noseman,

I cannot thank you enough for taking the time to prepare and share this project file! I have been struggling with this exact setup for days, and your solution is an absolute lifesaver.

I truly appreciate the effort and dedication you put into helping me out. I am incredibly relieved and happy to finally see it working the way I imagined!

Thank you again for your amazing support.

Best regards,

Hello everyone,

I'm trying to create a continuous thread/yarn that emits from a source, falls, and coils naturally on a collider surface.

I attempted the technique shown in this video (https://www.youtube.com/watch?v=Z4TJp95T6ys) using an Emitter, a Matrix object, and a Tracer to generate the geometry. However, my setup doesn't behave like a cohesive physical thread from the point of emission. Instead of piling up and stacking naturally, the geometry stretches out and doesn't act like a continuous rope once it hits the floor.

Here is a screen recording of my current progress and the exact issue I'm facing:

Is there a specific setting in the Tracer/Matrix setup I am missing to keep the thread intact? Alternatively, would it be better to approach this using the Unified Simulation system (like Rope Dynamics) rather than standard particles, considering I want realistic coiling physics?

Any guidance, tips, or quick scene file examples would be greatly appreciated. Thanks!
