[RELEASED] Liquid Physics Approximation

Hi everyone.

My new asset Liquid Physics Approximation has been released on Asset Store.

This package allow you to create a container with a liquid moved by a simple physics.

This effect it offer a good visual effect with low performance impact, and include customized liquid weight/density and many more features.

Hi everyone.

Version 1.1 has been submitted. Changelog:

- Script variable placement has been changed to arrange a separated section for every feature of asset (glass settings, liquid settings, and relative patterns and animations type).
- It's now possible to choose which color use on top liquid face.
- It's now possible to choose custom bubble patterns to apply in the containers.
- It's now possible to choose custom static animation patterns of liquid.
- It's now possible to apply texture gradient on liquid.
- It's now possible to disable/enable (already implemented) glass translucency pattern, and choose a custom tiling for it.
- It's now possible to choose custom UV animation patterns for glass translucency, with/without UV direction movement.

RELEASED!

 

Hi H92,
Is it possible to adjust the fill amount dynamically with scripts?

 

This seems to be interesting but it seems but the liquid seems to be too rigid, and it looks more like ice moving than liquid

 

Yes. If you want you can create a new script, with custom math to adjust fill amount (this type of things are possible with all public variable).

 

A more realistic water movement can be done with particles, but this method use clipping plane to generate that..

But maybe I can add a further cut to make this more smooth.

Hi everyone.

Version 1.2.1 has been submitted. Changelog:

- Static animation direction now follow main camera.

RELEASED!

 

I clicked the asset store link and is says the asset is deprecated. That seems a little odd doesn't it?
This looks so cool though! I'll check back to see when it's available again.

 

Yes sorry for this momentary inconvenient, I have deprecated it because the publication was wrong. Anyway I have already submit a correct package, which will be available in a few days (or hours).

 

Hi everyone.

Hi H92
I use unity 5.3.6f1, and plugin 1.2.5
But the shader seems broken, is there need to change any settings?

 

Version 5.3.6 is not more supported. You must upgrade to 5.4.1.

 

Hi everyone.

Version 1.2.7 has been submitted. Changelog:

- Fixed a bug where liquid volume not correctly change during object rotation.

RELEASED!

 

I would like to have a completely invisible container and transparent liquid. However, I can't seem to figure out how to achieve liquid transparency. Any pointers? Also; is it possible to use other shaders like the Standard shader for materials? Thanks!

 

At the moment you can't change opacity of glass or liquid (I understand well?), but I can implement it in the next version.

About standard shader, nope, you can't use this like material, because this shader doesn't contain mesh clip code

 

Hi everyone.

Version 1.2.8 has been submitted. Changelog:

- You can now set trasparency of: glass, liquid and bubbles pattern.

RELEASED!

 

Hi everyone.

Version 1.2.9 has been submitted. Changelog:

- Multiple bubbles mesh has been deprecated due to visual inconsistency.
- Various bugfix on bubbles system.
- You can now set bubbles rotation in x and y axis.

RELEASED!

 

Using this in Unity Beta 5.5.0f2 and it works really well! Few pieces of feedback that would make this product even better:

1) Is there any way to simulate lighting based on ambient light and a rough approximation of shadow at the origin of the liquid? I don't need 1 : 1 lighting, which I imagine would ruin performance, but right now I can't use it in really dark levels because the liquid stays the same lighting regardless of what is around it. In a pitch dark scene I can clearly see the liquid from a distance when it should be dark.

2) I can't seem to get bubbles to work yet. When I turn them on I just see a pink fill where I imagine the shader would be; I imagine this is because I'm using Beta 5.5 (or doing something stupid), so I imagine this is a temporary thing

Thanks for the hard work, looking forward to future updates!

 

Hi.

1) Yes, seems that I have forgot to sum liquid color to light/ambient color. Anyway I will check this.

2) This instead seems a shader problem (obviously). Maybe you must wait another Unity beta, in every case I will try to fix also this.

 

Hi everyone.

Version 1.3.0 has been submitted. Changelog:

- Color of cruet and liquid it's now based on light color.

RELEASED!

 

Wow thanks so much!! Going to make good use of this asset. Thank you for all your hard work

 

Hi everyone.

Christmas Update Version 1.3.2 has been submitted. Changelog:

- Internal smoke effect has been added.
- Fixed a bug on minimum liquid amount.
- Fixed a bug where liquid bubbles material doesn't work properly.
- You can now choose UV speed and tiling of liquid gradient.

Hi H92 -

I bought your asset today. I am trying to apply the ContainerManager to a cylinder but I am getting very strange results. By default (Amount = 0.5) the container already looks full, and if I bring amount to 0 then it is about half full.

I've tried moving the pivot but I'm not able to find settings where the container looks both empty at 0 and full at 1.

Any hints appreciated!

 

I will check soon or tomorrow.

 

Hi everyone.

Version 1.3.3 has been submitted. Changelog:

- Amount offset calculation has been rewritten.

RELEASED!

 

Works better with a cylinder now, thank you!

I'm trying to come up with a way to simulate pouring the fluid out of the container - is there any way to identify the point where the fluid comes in contact with the top of the container?

 

You can create a cruet parent object, that move local Y-axis (and also in X and Z axis to improve distance recognition) following mesh surface with raycast.

 

Good idea, thanks a lot for the quick reply!

 

You're welcome

 

Hello H92,

congrats on a neat looking asset. And I see you are very active in updating it and responding to comments. All great things!

I am planning to use it for a box that will be thrown in the air, and will then land back on the plane.
While in the air it will rotate around 1 axis, before finally landing with some amount of force.
I just need to hint that there is liquid inside the box, it doesn't have to be real-life liquid result.
I am curious, do you think I can use this asset for my situation?

Thanks a lot!
Kreso

 

I can not say what exactly do you search for your project, I can only tell you to view the demonstration video in this thread and make your choice. Or to buy the asset and request a refund if it is not to your liking.

 

Hi everyone.

Version 1.3.4 has been submitted. Changelog:

- Shaders has been updated with Shader Forge 1.35 (that include the meta pass for light bounce).
- Added options Metallic and Roughness.
- Files structure has been updated without "Standard Assets" folder.

RELEASED!

 

Hi everyone.

Version 1.3.5 has been submitted. Changelog:

- Shaders has been updated with Shader Forge 1.37.
- Added option to completely hide glass.
- It's now possible to disable the static animation by removing the pattern.
- Various bugfixing and performance improvements.

 

Hi, the asset seems interesting, are there any videos of it in action?

 

I had some problems with videos. If you want buy it and try, and after do a chargeback.

 

Advising someone to buy your product instead of spending a little time on promo video, Epic fail.

 

There was a video before, but I had some problems with the account on which it was hosted.

At this point I will build a demo scene and update the main post...

 

Hi everyone.

Version 1.3.6 has been submitted. Changelog:

- Various buxfing in runtime.
- Added a Demo Build (first page).

RELEASED!

 

Should this work on iOS?

 

I haven't an iOS device, so not know.

But on ShaderForge there is the support for Metal, so I presume that can work.

 

Hi, It looks like the material and animation don't work in Arkit. When I build it in iOS, all material becomes default grey solid material and there is no animation or flowing water.

 

I tried in ARkit, it won't work in ARkit.

Hi everyone.

Version 1.3.7 has been submitted. Changelog:

- Fixed a bug where container appeared destroyed and reported on console.
- Added a bool value to enable or disable light color on container.

RELEASED!

 

Can anyone confirm if this will work on Android or iOS?
I'm looking to simulate liquid physics inside a bottle and/or cup with a rigidbody.
