Trying to recreate similar liquid effect as in Daredevil's intro

[Zakkorn]

Hello,
as the tittle says I am trying (sort of) to recreate that effect of how the liquid drops on an object's surface.
The problem I am facing (at the moment) is that I cannot make the liquid have long drops or I cannot make the drops "hang" from the bottom of the object till they fall.
You can have an idea on the image I posted.
I played with Surface tension, scene scale, particle size, Viscosity, SPF.
ut there is no way to get near to that.
Can anyone help me on this, because is about a project I am on and I will be out of time soon.

I include the scene file, for anyone that want a starting point to play with.

Regards,
Zach

Hey,

You can try to play around with the Droplet breakup value - lower values will make tendrils while higher values will produce droplets.

[Zakkorn]

I tried that as well.
No big difference. Not even close to what I want to achieve.
You can see in the image that the liquid falls and make stream. Its not dripping like the blood effect on Daredevil's intro.

So no one can help me.

I'd say the guys in elastic probably had animated geometry for the long, thin bits and either ran liquid over them or just spawned particles on them and put the same metaball surface on top to blend the lot in.

Hm, can someone share the original watery reference? Not sure Im following.

They did it in a non physical way - don't be afraid to make some animated elements, render them with the same shader as your fluid and combine it in comp, it'll be quicker and more direct! I've even done fluid drips like that using an animated cylinder for the long part of the drip and a sphere at the head of it, you can put both objects into a blobmesh object and it'll web the two of them together - then you can use regular max lattice and relax modifiers to get really specific movement and timings.

[Zakkorn]

So you mean that the drops they were hanging were just extra animated geometry, and combined it with the liquid sim, right?
Hmm interesting.
Is this means that the liquid sims can not achieve the real-life liquid behavior yet?
As the drops in reality would hang a while first, (till their "tentacle" break because of the "elasticity" that reach a limit) before they fall. (in paint or blood liquids).

Hey,

It's a way to gain easier control so you can save time in setting up the simulation.

I don't see anything in the daredevil video that you can't achieve with Phoenix. Is your droplet radius 0.3? If you want to get such big fat drops, you need much more than this. Here is the documentation about the surface tension settings: https://docs.chaosgroup.com/display/...SurfaceTension

As we spoke in the other thread - increasing your scene scale will make the simulation unfold more slowly, so this would also help the droplets hang longer.

Cheers!

Svetlin.Nikolov I tried bigger scene scale, but the Liquid doesn't "stick" and hang from the bottom as we should expect according to the laws of physics. But it just falls.
I reduced the gravity to 0.1 and still it falls like it weights 2 tons.
I cannot realise what I am doing wrong or what I have to play with to slow it first and then it should hang up like a tentacle and then drop.

Have you enabled Wetting and Sticky Liquid?

[Zakkorn]

Have you enabled Wetting and Sticky Liquid?

Yeap I did.
But no difference on the way the liquid falls.
It didnt gave the feeling that sticks and goes slowly down.

[Zakkorn]

So to make things more clear.
Is it possible with PhoenixFD to achieve a drop movement like in the image?
And How?

Roger that, let me try to set up an example for you when I'm back in the office..

[Zakkorn]

Great!!!

I really appreciate it, Svetlin
