I subscribe to several guys building game engines that use youtube to showcase their work – the ‘Wicked Engine’ being one of my favourites, there are prolific updates that often show cutting edge game engine rendering.

Recently a video popped up showing underwater caustic simulation and it is actually a pretty good case of ‘fakery’ (isn’t all game build fakery of sorts though). So using that as inspiration I delved in to the open source to see if I could replicate/duplicate in the ‘Cogwheel Engine’.
