Ink in Water

This is just another test to simulate a real ink (not a pseudo smoke driven inky something) liquid inside of a water liquid.

The flow is completely driven by variable density. No other external forces or anything used. The ink here simply has a higher density than the water.

However, some forces would probably be good to make this more interesting. Also the rendering was done by generating a mesh out of the liquid particles. It would be interesting to see how a volumetric smoke render from these particles would look like. I might re-render this accordingly at a later time.

This is exactly what ive been looking for in order to buy this plugin, a tutorial would be great and swing it for me,

@acocobilly

You can see a tutorial of the technique here: watch?v=peyGhUa2duM

I find myself in a moment in which I have to decide between 2 plugins to buy... and this kind of stuff does make a difference, but I downloaded the demo and have no freaking idea of how to set up densities like you describe. Could you please share the c4d file or maybe give me a further insight of how can I archieve this? Thank you

Hi, it's very easy to set up. In the "fluid" tab of the liquid solver, change the properties type from constant to variable. Then check the option "density" that appears afterward in the same tab.

Now you can let emitters emit a different density. That's all, 2 clicks. There will be a short introduction to variable properties in a tutorial soon.

Tried the variable density tutorial, got a blob falling slowly, long way off this, which is the main reason i bought. Pleeease a tutorial on this with mesh, tex details

[rekabalint]

you say that all it takes is variable density, but it doesn't work, i;ve tried 1200, 2000, 5000 density for the ink but it just won't dissolve like in this video, and also what texture did you used?

that bubbles tutorial doesn't explain this ink effect, that's a total different setup!

Activate variable density in the solver. You create a big emitter (water) and then you create another emitter (ink). Create a FSS Particle Group (from within the solvers particles tab). Let the second emitter create the water particles into the particle group and with higher density. The first one into the global group and lower density.

@BlueSageDave thx

@DaFman

thx! :) My references were rather these:

watch?v=Pfs0nxXm-e8

watch?v=VPBdsIWyUZk

It shows hardly any diffusion or mixing so I thought a mesh would be most appropriate to catch this and actually avoid mixing.

@DPITNatureSpirit how the heck do I go about creating Ink though ?

@steadiworkz

Sure the demo is fully functional.
