Hi Pim,

Here is a starting point. Explore how different Noise and Seed versions affect the distortion (animated), while the scale is surely a strong influence.

I have set the ramp to match your reference image.

Back in the days when I made stage light shows for bands for many years, I had one of these Oil projectors that created this effect. There was a round double glass chamber, each filled with two tinted oils. After the light warmed the oil, it produced all these psychedelic patterns based on a little motor rotating the unit with the oils, and the patterns changed. When combined randomly with my other nine projectors, it created a nice blend. Why am I talking about stuff from decades ago? Because the two chambers are a key point here, and I have set the Material up in that way, with two sources mixed in the Color Layer.

All the best

Hi Pim,

The Fracture Object is needed to get Single Clones from the Sweep. I produced the Path (for the Sweep) with the Cloner and then used the Sweep. This is a needed step if the Sweep Profile should stay the same diameter but the Path diameter grows.
The Fracture takes it apart to access the ID.

The number of objects, in which way, the ones visible pre-frame or in total over time, and from which file? If you have the Forumla only here in mind, use a Cloner. (Do I get the question at all correctly?)

The Constant Frame, in the file set to ten frames. If they should progress faster use a smaller number.

Let me know if that clears the questions.

The formula
(pow(2;trunc($1/$2)))*$3
It is a Power function, that has one variable as Truncate in it. The $-numbers are the input values.
I'm sure you are aware of this information, but for anyone reading along, and is new to it:

Hi Pim,

In the scene, you have two needs: Progressively vanishing polygons and producing particles only on the event horizon when polygons disappear.

In the first half of the screen capture, I show what happens if that is not limited to the particular line.

In this way, two Fields take over each of the needs.

The one for Particles is used in the Polygon Selection to define where the Surface Emitter should produce new particles.
Example

Let me know if that helped.

Cheers

You're very welcome, Pim; thanks for your interest and patience.

I used the Character Object to Weigh it - automatically, which needs a little more care in this case. Hence, I shared only the Geometry.

If you have any other questions, please open a new Forum thread.
I'm happy to look into it.

Enjoy

You're very welcome, Pim.

Thanks for taking the time.

My best wishes for your project

Hi Pim,

Keyframes move the Balloon in the scene that its parent Null has; it is not a Simulation.

I have no idea how to keep the length of a Rope the same. I was in a more extended session with some other Master Trainers and asked, as I thought I might have missed something. The answer was that it is not a feature in the Simulation system. An indicator that it is not fully developed is perhaps that it has so far no connectors, like Springs, that I usually use for balloons and similar setups, see below (And yes, the string is behind. This needs to be baked and adjusted.

I would animate the Balloon as needed and the rope's end, then connect the two. But that is just me.

All the best

Enjoy the exploration, Pim!

My best wishes

Thank you very much, Pim,

This feels like sitting in a cinema theater. Love it.

Very nice of you to take the time!

My best wishes for your project
