You probably won’t find too much information about them at time, since they haven’t been available to the public prior to the UE4 integration. Also the WaveWorks integration was (from what I can figure) just started, so not all the implementation was done. I am nearly done with the QuadTree infinite plane WaveWorks implementation now, so once that becomes available, it will allow you to just drop in an endless ocean, and create a material to suit.
Just need to fix the state getting destroyed after rendering the WaveWorks object, Edge tessellation, VertexFactory input layout, and then its ready to be released. I will also say, breaks all original WaveWorks functionality, so it can no longer be applied to arbitrary objects. I will eventually provide a plane based object for smaller bodies of water.
