I am trying to simulate below picture / animation.
It is a simulation of fluids mixing (often used in light show at pop concerts).

So the main thing is how to 'mix' textures in cinema?
I started using the Proximal shader, but it is very complicated.

I hop someone can help me.

Great!
The first solution - using the visible option - gives me what I want.
The second solution is very complex. Some quesions about it:

• why use a Fracture?
• how to increase the number of objects / circles
• how to control the speed.
  I guess speed is 'according' to the formula.

The Xpresso is indeed very very small!
That makes the Formula rather complex.

Thanks for all your help.

I managed to do it with 2 Fields.
One 'turning on' the circles and one 'turning off' the circles.
Thus seeing only 1 circle.

However, it is not that smooth.
Do you have any suggestions to improve?

scale circle with 2 fields v01.c4d

I took your idea to use a Formula, but I used xpresso.
Now I can scale the circle, stepwise every 10 frames (using the mod() funcion in the formula).

Is this a good solution, or do you think doing it another way is better?

Here is the project file.
scale circle v01.c4d

Hi Dr. Sassi,

Thanks for the reply.
That solves the reply on the stepwise moving and scaling.

But I only want to see the last one, not the previous ones.
How to do that?

Hi,

I have one circle (in a sweep) and I want to move and scale that circle stepwise.
So, do the following in a loop:

• move circle, 100 over Z axis
• scale circle, uniform scale = 2
• wait 25 frames

I tried to do it with MoGraph, using different effectors like Plain or Step (with or without Fields), but no success.
The main question is, I guess, how to show only one clone and not all the other clones?

@Dr-Sassi Oke, I will limit to height of 500 pixels and scene size of 1 Mb.

Another thing I noticed is that my version is not working because the new second Field was not added to the Polygon Selection Tag of the Text.1 object.
After adding it, it worked.
I do not fully understand why this is needed?

PS I also noticed that I have to update my knowledge on fields.

@Dr-Sassi Sorry, I do not fully understand.
I tried to recreate the setup, by replacing your 'Linear Field.Particles' with my own Linear Field.
But that does not work.
The text is 'hidden', but no particles are generated?

I think I use the same setting as in your 'Linear Field.Particles',
but apparently one of the settings is wrong.
But which one?

PS I tried to upload a picture and a scene file, but I get below errors.
The jpg file is 90kb and 443x800.
The scene file is 1500kb. If I make it a zip file, I get a invalid type error?
xxx.c4d Unspecified error when uploading scene file?

@Dr-Sassi I am beginning to see the light!

I have now a text that is dissolved and particles are emitted.
However, particles are emitted from all polygons.
Only the polygons that are 'dissolved' should emit particles.

What am I doing wrong?

dissolve text met mesh emitterv 03.c4d

I started to look at the tutorials and one of the things I see, is that I have an old version.
I upgraded to R2024.5.0 and now the plugins are there.
