  You could probably get pretty close with the new liquid system in C4D plus some particles for the foam/bubbles.

  Broadly, I’d approach it something like this:

  • Start with a circular emitter in the center of the jacuzzi.

  • Emit liquid upward with a bit of turbulence.

  • Use a Rotate Force or Field Force to create the spinning whirlpool motion.

  • Add extra upward velocity/turbulence near the center so you get those little splashes and chaotic bubbling areas.

  • Then layer separate particles for foam/bubbles on top rather than relying purely on the liquid sim.

  For the foam you could either:

  • Render tiny particles directly.

  • Or generate a secondary foam pass using particles + sprite materials.

  • Or use vertex maps/fields to drive foam shading on the liquid mesh.

  Also worth checking out LiquiGen — it works really well with C4D and honestly feels more flexible/faster than the native liquid system in a lot of cases.

  The looping part is probably the hardest bit unfortunately.

  A perfect seamless liquid loop usually means messing around with mesh morphing/cache blending or carefully syncing the sim state. Depending on the shot length, honestly a subtle fade/crossfade between loops might be the easiest and cleanest solution.
