How to create a realistic looking Ink spill from a bottle? I've been working on a project for the past couple of days and I would like to know a way to create a realistic ink spill/splash from a bottle.
I tried using Mantaflow and it came out looking like this.
It doesn't quite look like ink. I used the viscosity of water and also reduced the upres value.

What I'm actually looking for is something like this or atleast close to it.

I would also like to know how to create the tiny particles or residue inside the bottle left by the ink. I tried duplicating the entire inner portion of the bottle and adding another material to it. But it doesn't work.
I hope somebody looks into this.
You could also try volumetrics and an image texture.

Use an image texture for the color bleed
Give your ink spill a Glass Shader and a Principled Volume shader
Use a texture to drive the volume's Density (there's more ink on one end)
