Fake Liquids Documentation

How to Install:

Installation is really simple. Simply add the blender file as an asset library. You will then find the modifier and some example materials under the "Fake Liquids" category inside of Blender's asset browser. The example materials are directly linked with the modifier, so you will need it to properly preview them.

*IMPORTANT*:

***You must play the timeline to see the liquid appear ***

Fake Liquid Modifier:

The Fake Liquid modifier is a geometry node set-up that contains a lot of customization and settings. Below you will find what every setting does and how to use it.

Bottle:

The bottle category is responsible for the bottle itself.....

Liquid:

This category is responsible for defining the visual appearance of the liquid, from movement, surface tension, foam and bubbles.

Movement (liquid):

A sub-category of the liquid settings, which controls the movement and viscosity of the liquid

Surface Tension (liquid):

A sub-category of the liquid settings, which controls the visual appearance of the liquid's surface tension

Bubbles (liquid):

A sub-category of the liquid settings, which controls the fizziness and appearance of bubbles within the liquid. Useful for carbonated drinks.

Foam (liquid):

A sub-category of the liquid settings, which controls the visual appearance of foam. Useful for liquids like beer.

-----------------------------------------------

Material set-up:

This part of the documentation isn't necessary, but it's useful to know how the custom nodes work in case you want to create your own materials or build on top of the ones I provided

Liquid Logic:

The Liquid Logic node is the core of the shader. It grabs the attributes provided by the modifier and works shader magic on them. 

Mix Liquid and Foam:

This custom node is responsible for mixing liquid and foam, taking into account appropriate normal mixing and foam attributes from the geometry nodes set-up.

-----------------------------------------------

Limitations:

As expected, there are some limitations with calculating liquids in shaders instead of proper simulations.
