While there are plenty of online tutorials out there on underwater effects very few of them help with creating the effect of being near the surface where volumetric rays are cast down and when you look at the waves above the refract the skybox and even look reflective at some angles.
I am not too worried about the wave simulation part of this it is the part afterward that. I just can't figure out what terminology would get me good search results for how to do this.
Does anyone have any pointers on how to achieve this effect? Technically this is specifically for a Unity environment but I figure the general techniques would be rather portable to Unity.
