Water and foam

A set of procedural materials of water and soap foam

A set of three materials (water, foam and bubbles) works together.
You need to copy your surface into itself (without offset) twice.
In total, you should have 3 surfaces (the original and 2 copies) in each other.
Apply water material to one surface, foam material to the second, bubble material to the third.
The material is completely procedural, does not contain textures and is created exclusively with the help of procedural maps.
The materials library contains 3 versions of materials with different foam densities - low density, medium and high.
The materials library contains 2 versions of materials for different units of measurement of your scene - millimeters and centimeters.
Use the version of the material that corresponds to the units of measurement of your scene. Otherwise, the foam will be at the wrong scale and will look different from the preview.
The material is configured using Displace, so its behavior on the object directly depends on the geometry of the object itself.
The material is demanding of computing resources - rendering can take a long time on weak computers.
