Blender Water Shader effect

This is a simple scene to render polar waters.

To make the cube look like water, mix the following shaders:

1. Glass BSDF Shader : Roughness = 0.850 , IOR = 1.010 ~ 1.333 and Color = Blue
2. Mix Shader : Factor = 0.500
3. Translucent BSDF Shader : Color ~= 2B9489 (a bit dark greenish blue)
4. Transparent BSDF Shader : Color ~= 3173C0 (bluish)
