Map im working on for a game.
The water was made using only the terrain editor and some cool lighting. The white streaks in the water were made using the flatten tool. I increased the saturation a bit to really bring out that cartoon/ghibli vibe. I still have to add the streaks in other parts of the water as well, maybe adjust the colors of the water and streaks.
You can do some really cool things with the terrain editor/lighting.
Here is another map im working on. Well a river. Again i was going for the cartton/ghibli vibe.
I have saw a tutorial of this on youtube.
