inspire by 则卷大明's Unity3D-移动平台简单水效果的实现 and AoE2HD
the water surface texture i used is come from AoE2HD,so i can't include in the project.
also make sure to import the noise texture as a normal map in your project.
and mark the sunlight texture warp mode to Clamp.
if you curiousness on how i made this shader,please check more info on my Blog
