Can you suggest me on how I can achieve these following functionalities with liquid simulation :. The volume of liquid to be filled is a variable, which will be decided by the user. Liquid inside a bottle and it has to move depending on how the bottle is positioned in 3D. I had tried with Stencil buffers, particle system, Cloth component etc. But couldn't achieve with any of them. The problem with particle system is that, it is heavy performance and the particles are leaking out from the sharp edges of the GameObject's mesh, even though the Collision is enabled for the particle system.

Joined: Jun 25, Posts: I'm just posting to announce our new asset is released on the asset store! We've spent a lot of time effort and money on creating this asset and we hope you enjoy it! It's an easy to use tool that allows you to create advanced physics based games and simulations within the unity engine. It can simulate tens of thousands of particles in real time to create realistic fluid effects.

Price seams fair if a bit out of my personal range. It would be cool to see a "light" version with a lower price point but more limited functionality. Anyway nice work, fluid simulation is so cool!

Is it possible to have a quick description of what these licenses say? Also does the system require Unity Pro and does it support refraction in the water? Last edited: Jan 23, Hi, both licenses are very basic.I'm making a game that uses liquid particle physics so that water and other liquids can pool and form blobs similar to the physX demonstrations.

The question is how to make the individual particles render as a single sheet of water in indie unity. Do I need to use a mesh that wraps around groups of particles? A method which could probably be implemented in Unity would be to treat the particles as " metaballs " and render their combined surface using the Marching Cubes or Marching Tetrahedron algorithms.

Did anyone end up implementing the metaball particles? I would love to use something like this in my game but I'm new to graphics programming and have no clue where to start as far as "rendering their combined surfaces".

The spawner must be minuscule.The Unity Standard Particle Shaders are built-in shaders that enable you to render a variety of Particle System A component that simulates fluid entities such as liquids, clouds and flames by generating and animating large numbers of small 2D images in the scene.

More info See in Glossary effects. More info See in Glossary. Select the Material you want to apply the shader to. More info See in Glossaryselect Shader Particles. The Standard Particle Shaders have the same set of properties as the Standard Shader A built-in shader for rendering real-world objects such as stone, wood, glass, plastic and metal. Supports a wide range of shader types and combinations. More info See in Glossary or a subset of those properties, depending on the Shader.

This page describes the properties and options that are additional to the Standard Shader properties.

Liquid Particle Physics Rendering

For information on the Standard Shader properties, see documentation on Material parameters. All of the Standard Particle Shaders have Blending Options that enable you to blend particles with the objects surrounding them in different ways.

This shader comes with functionality similar to the Standard Shader, but works especially well with particles. Like the Standard Shader, it supports Physically Based Shading An advanced lighting model that simulates the interactions between materials and light in a way that mimics reality.

It does not include features that are unsuitable for dynamic particles, such as lightmapping. It supports all of the generic particle controls, such as flipbook blending and distortion, but does not perform any lighting calculations.

Legacy Shaders. Publication Date: Rendering Mode A Standard Shader Material parameter that allows you to choose whether the object uses transparency, and if so, which type of blending mode to use. The Standard Particle Shaders can have the following Rendering Mode options, which control how the final color from the shader is combined with the background color: Additive : Adds the background and final particle color together.A particle system A component that simulates fluid entities such as liquids, clouds and flames by generating and animating large numbers of small 2D images in the scene.

More info See in Glossary simulates and renders many small images or Meshes, called particles, to produce a visual effect. Each particle in a system represents an individual graphical element in the effect. The system simulates every particle collectively to create the impression of the complete effect. Particle systems are useful when you want to create dynamic objects like fire, smoke, or liquids because it is difficult to depict this kind of object with a Mesh The main graphics primitive of Unity.

Meshes make up a large part of your 3D worlds. Unity supports triangulated or Quadrangulated polygon meshes. Nurbs, Nurms, Subdiv surfaces must be converted to polygons.

If you are used to working in 3D, Sprites are essentially just standard textures but there are special techniques for combining and managing sprite textures for efficiency and convenience during development.

Isometric Liquid

Turning on a valve would allow the water to fill the pipe to the next valve. How would one go about doing this? CalhoonDec 17, Joined: Dec 3, Posts: I'm sure there are lots of ways to tackle this. The first thing that came to mind for me is: 1. Create a water particle system to simulate water flow. Probably keep this short for each pipe segment. Attach a script to the water particle system that links a parent water system to it.

This way a "chain of water" can be created running through any sort of combination of pipes and valves. The key being if this particle system stops emitting, all children will stop emitting too. Attach a script on each valve to control the flow of water, or basically the emission of each water particle system. Meaning, if this valve is off all child water particle systems will be off too using the chained water links from above. Checking the status of whether or not the enableEmission flag is set in each parent particle system is lightweight too, so it could run every frame if necessary I think.

I'm new to Unity. Was experimenting with particles but thought I was on the wrong track. I'll mess around with them some more. CalhoonDec 18, Joined: Jun 5, Posts: If I need to do as particles to rotate on circle path 3D gameplay.
