Just thought I would throw in a couple of things. I can’t get most of the water features to work regardless of UE5 or UE4 as I am using heightmaps from World Creator. Water Custom does work however and I have had some success with that one. On Early Access 2, I have a large terrain created by using tiled heightmaps and have a ~8K terrain that I can load parts of and this is actually working nicely so far. I do have a 3090, 128GB of RAM and 16 Core AMD processor and I can get around 100FPS when I load different parts of my terrain. I really want to get the lake and rivers working properly but they just don’t so far. They are not visible and nothing I do in UE5 makes them show up yet. I can update if you want if I find a solution.
