Hi again DR Sassi,

I've hopfully got 1 last question about liquids for you!

I'm trying to pour some icecream onto a plate by swirling an emitter.

It works ok, but do you know if theres a setting I can use to make the stream of icecream keep its shape better? The emitter is a star shape and I'm trying to get that classic soft-serve icecream look, not a big blob like Im currently getting.

Here's my attempt so far: https://we.tl/t-eI5ILJ20ZN

Thanks again!

It might be that liquid sims created in c4d 2025 go crazy in 2026. I just know that when I run the same file in each version the particles in 2026 just shake uncontrolably.
Here's a video showing it, exactly the same file open in each: https://we.tl/t-hjoXhyfScF
I'll just go back to 2025, always a bit risky to upgrade mid job;)

Hi Dr Sassi, I ended up trying my scenes out back in c4d 2025 and it works fine, it looks like the liquid simulation system is very buggy in 2026. I tried multiple old scenes and they all go crazy in 2026.

I reported it to Maxon but as usual they just brush me off.

Thanks heaps for helping me trouble shoot this, Im close to getting in finished now!

have a great weekend!

Thanks again for that, I played around with the particle sizes and ended up scaling up the whole scene which kind of fixed it.

But one thing I cant seem to fix is some particles randomly popping and shaking up and down.

It must be a sim quality setting or something but again, no matter what I try it wont stop shaking.

Here's my file and a video showing the problem, any ideas? So close to finishing this one!

Gunius! That works great, thanks for that, again I never would have thought of that!

One quick question though, I've tried to recreate this but I've noticed the particles are intersecting. Especially around the edges of the heart shape as you can see from the attached screenshots from your project file (Seen in the closeup too).

Is there a way to increase the accuracy of paricle interactions without using rigid body which will remove the liquid look? I tried increasing substeps and collision passes, iterations, but it doesnt seem to have any effect on the particles.

Thanks again

Hi again Dr Sassi, quick question,

with the particle system in C4D, is there a way to have the particles try to return to their original positions after being pushed away? Similar to what Mix Animation would do to lLoth or Folow Position would do to Rigid Bodies?

I'm trying to create this effect https://www.instagram.com/reel/DOehIU0Egxq

But I cant get it a smooth, its almost liquid like.

Here's my attempt anyway, I couldnt do it with particles alone so I tried to do it with a mix of Rigid Body, but its not so smooth.

Im sure theres a particle tool that will do this but I cant find which one.

Thanks again

Awesome, exactly what Im looking for! Never would have thought of Conditions! Thanks again for your help on this one

Well there you go, I was using 2025.3.3 and it wasnt working at all, just tried 2026 and it works perfectly, so I guess it was a bug.

But I see a lot of new bugs in 2026, I just can't win;)

Thanks again for this, was tearing my hair out - I did try r 2024 which also failed, so I guess they fixed it recently.

Cheers

Hi again Dr Sassi,

Following on from my previous problem, Im trying to create a turbulent ocean with the fluid system and particles.

I've made a black and white mask with a color mapper from the velocity of the water, but I cant figure out how to generate a new set of particles from the velocity of another particle group (specifically the remapped values from the Color Mapper).

Ive tried the data mapper and reproduce, and all the other emitters, but I can figure out how to drive another set of particles from the white points in the color map.

Any idea what tool I should use to do this, or if this is even the best way to make realistic looking Ocean foam (I guess I'll do a lot in the shader as well)

Here's my attempt so far: https://we.tl/t-MZAAYIRACy

Thanks again!

thanks for that, I've tried rearranging them and removing the ramp but I still cant get it to show up, caching doesnt seem to have any effect either.

Should the order top to bottom be Mesh Objects, Particle Group, Turbulence, Liquid Fill Emitter, then Liquid Mesh? In my mind that seems to be the logical order, but I still cant get it to work.

Have tried rendering in picture viewer, and also simming with CPU instead, but nothing.
