#NVJOB Water Shader - simple and fast 1.4.5

nvjob.github.io/unity/nvjob-water-shader

Simple and fast water shader. This shader is suitable for scenes where water is not a key element of the scene, but a decorative element. Supported rendering path deferred and forward. It works on all platforms.

Prerequisites

To work on the project, you will need a Unity version of at least 2019.1.8 (64-bit).

Information

The movement of the waves is carried out using global shader variables: _WaterLocalUvX, _WaterLocalUvZ, _WaterLocalUvNX, _WaterLocalUvNZ.

_WaterLocalUvX, _WaterLocalUvZ - Offset main texture.
_WaterLocalUvNX, _WaterLocalUvNZ - Offset normal map texture.

An example of a script for the movement of water.

using UnityEngine;

public class Water : MonoBehaviour
{
    public float UvRotateSpeed = 0.4f;
    public float UvRotateDistance = 2.0f;
    public float UvBumpRotateSpeed = 0.4f;
    public float UvBumpRotateDistance = 2.0f;

    Vector2 lwVector, lwNVector;

    private void Awake()
    {
        lwVector = Vector2.zero;
        lwNVector = Vector2.zero;
    }

    void Update()
    {
        lwVector = Quaternion.AngleAxis(Time.time * UvRotateSpeed, Vector3.forward) * Vector2.one * UvRotateDistance;
        lwNVector = Quaternion.AngleAxis(Time.time * UvBumpRotateSpeed, Vector3.forward) * Vector2.one * UvBumpRotateDistance;
        Shader.SetGlobalFloat("_WaterLocalUvX", lwVector.x);
        Shader.SetGlobalFloat("_WaterLocalUvZ", lwVector.y);
        Shader.SetGlobalFloat("_WaterLocalUvNX", lwNVector.x);
        Shader.SetGlobalFloat("_WaterLocalUvNZ", lwNVector.y);
    }
}

For working shaders on mobile platforms with Forward Rendering.

In asset this fix is already added to the general script.

using UnityEngine;

[ExecuteInEditMode]
public class depthTextureFix : MonoBehaviour
{
    void OnEnable()
    {
        GetComponent<Camera>().depthTextureMode = DepthTextureMode.Depth;
    }
}

The rotation of the wind synchronously with water (optionally).

using UnityEngine;

public class WindZoneRot : MonoBehaviour
{
    Transform tr;

    private void Awake()
    {
        tr = transform;
    }

    void LateUpdate()
    {
        tr.rotation = Quaternion.LookRotation(new Vector3(Shader.GetGlobalFloat("_WaterLocalUvNX"), 0, Shader.GetGlobalFloat("_WaterLocalUvNZ")), Vector3.zero) * Quaternion.Euler(0, -40, 0);
    }
}
