Unity HDRP Free Realistic Water

Simple water shader prepared with ShaderGraph in Unity 2019.3.1f1. Has still a lot more work to be done but still might be of use to someone so here it is :) Not likely to get updated frequently but will be updated eventually.

Update 5

A conributor just fixed a weird ripple issue that happened with camera movement. Merged the pull request. Credit: https://github.com/ryantwarner

Update 4 (Long time no see)

Renewed the shader to be compatible for 2019.3.1f1. Added a tiny tiny readme which also includes a link to my asset store page. (Because why not? :) )
Also added a .unitypackage file for convenience.

Update 3

Added a working scene file with an example

Update 2

Added wave controls and Edge foam settings.

Update

Added waving and a crude way of edge foam. Will improve but still should be useful enough :)

How to

Just drag 1 or 2 normal maps to the textures and have fun with the settings :)

Settings(Skipping obvious ones like the main color):

Top Color: The outside color of the fresnel effect.

Speed: Sets the speed of blending. Can get jiggy on high speeds.

AngleDim: Sets the power of the fresnel effect (The color changes depending on your angle of view)

Smooth: Specular smooth.

A lot of wave settings (Just tinker with them and you'll see)

Edge Alpha: Adds the alpha from this texture to the foam. Can be used to add some form of simple variance

Clamp Edge Brightness: You will need to adjust this especially if you have bloom enabled.

Edge Offset: How long is the foam?

To-do

-Preventing "intersection repeats". You'll notice probably after tweaking it some time.
