Stylized Ripple Water Shader
This stylized water ripple material works through the following steps:
​
Core Concept:
1. Noise Generation:
The material uses gradient noise to create the basic pattern for the water surface. The animation effect comes from combining multiple layers of noise with different scales and speeds, making the water ripples appear dynamic.
2. UV Distortion:
The Tiling and Offset node shifts the UV coordinates, simulating the movement of the water. As the texture moves over time, it creates the illusion of water flowing and rippling.​​​
3. Foam Effect:
The foam effect is generated by adding another layer of noise, often with smaller scale and faster movement. It uses depth information (calculated from scene depth) to highlight foam near the edges or in shallow areas, making it look more realistic.
4. Color and Depth Effects:
The color of the water changes based on depth, with deeper areas being darker and shallower areas being lighter. This is done using lerp (linear interpolation) to smoothly blend two colors based on the depth, adding depth and realism to the water surface.
5. Final Effect Combination:
Multiple layers of noise are combined using multiplication to control the wave motion, foam intensity, and overall surface deformation. The result is a dynamic, stylized water surface with ripples, foam, and depth variation.Result:By combining noise-driven movement, depth-based color changes, and foam effects, the material creates a lively and stylized water surface that looks realistic and expressive.
