I initially started looking at doing some wave assets back on the Mistshore map but ended up scrapping them as it was a hugely complex map already. This map I had a little more time to experiment with waves and spray/foam around the boat and decided to put together a wave asset pack.
The pack includes 5 large waves, 3 smaller (not fully cresting) waves, and a large assortment of frothing and foaming assets to add contrast to water maps and make them seem more fluid.
The zip below also includes the 6 DD map files for this location (autumn and summer are a combined version this time), the DD asset pack, and the raw png wave assets.
