由于Unity自带的水用起来实在不方便，而且效果一般，没办法只好自己重新写了一个，最终出来的效果感觉还想，如果觉得效果不好请勿喷。先上图，预览一下效果！

Shader：

Shader "Util's Shader/Water/Water Real"
{
   
   
	Properties 
	{
   
   
		_Color("Main Color", Color) = (1,1,1,1)
		_SpecColor("Specular Color", Color) = (1,1,1,1)
		_Shininess("Shininess", Range(0.01,5) ) = 0.01
		_MainTex("Base (RGB) Gloss (A)", 2D) = "white" {}
		_BumpMap("Normalmap", 2D) = "bump" {}
		_RefractionColor("Refraction Color", Color ) = (1,1,1,1)
		_RefractionDis("Refraction Distortion", Range(0,1) ) = 1
		_ReflectColor("Reflection Color", Color) = (1,1,1,1)
		_ReflectionDis("Reflection Distortion", Range(0,1) ) = 1
		_ReflectionTex("Reflection Texture", 2D) = "black" {}
		_Fresnel("Fresnel", Range(0,1) ) = 0
		_WaveSpeed("Wave speed (map1 x,y; map2 x,y)", Vector) = (0.2,0.2,1,0)
	}
	
	SubShader 
	{
   
   
		GrabPass {							
			Name "BASE"
			Tags { "LightMode" = "Always" }
 		}
		Tags { "Queue"="Transparent" "IgnoreProjector"="False" "RenderType"="Opaque" }
		Cull Back
		Lighting Off
		CGPROGRAM
		#pragma surface surf BlinnPhongGlass dualforward
		#pragma target 3.0
		
		inline fixed4 LightingBlinnPhongGlass ( inout SurfaceOutput s, fixed3 lightDir, half3 viewDir, fixed atten)
		{
   
   
			half3 h = normalize (lightDir + viewDir);
			fixed diff = max (0, dot (s.Normal*2, lightDir));
			float nh = max (0, dot (s.Normal, h));
			float spec = pow (nh, s.Specular*128.0) * s.Gloss;
			fixed4 c;
			c.rgb = (s.Albedo * _LightColor0.rgb * diff + _LightColor0.rgb * _SpecColor.rgb * spec) * (atten * 2);
			c.a = s.Alpha + _LightColor0.a * _SpecColor.a * spec * atten;
			s.Alpha = s.Alpha + c.a + c.rgb;
			return c;
		}
