So I'm trying to figure out a way to give an effect of two islands isolated in the middle of the ocean. Two of the obvious issues I'm going to have is #1 lots of water will be harmful to performance and #2 I want to use boundaries to prevent people from swimming off into the sunset and I can't really drop a fence in the middle of the ocean. To get around #1 I thought about using a limited amount of water around the islands or even just between them and then a 3D skybox showing infinite water but I can't seem to lineup skybox water with the real water. The skybox water level is normally below the normal water (maybe a problem with where I put the camera). Also the differences in textures is very obvious (doesn't fade from one texture to the next). And now with #2. I came up with 3 ideas so far. In the first one I have real accessible water between the 2 islands and unaccessible (maybe cheap) water bordering both sides and a clip preventing players from accessing it. And then a 3d skybox giving the effect of the water going on forever. The unaccessible water is to give a little buffer room for the water to fade/merge into the skybox water. Idea two is basically the same but gives more area to swim. Then there is idea 3 where there is no clip and the blue area is actually a damage trigger so if they decide to go too far they take damage or it could be fog and they just can't see beyond it and then i wouldn't need a 3d skybox with infinite water. Suggestions? The key for the images is: 1. Land 2. Accessible water 3. Unaccessible/Harmful water or fog 4. Clip border 5. Skybox The next hurtle will be dealing with depth of the water. I want it to look bottomless and I want any of the brushes (bottoms of islands) to fade into this bottomless pit. I believe water kind of already does this on it's own.
