I'm working on building my overworld (similar to the open areas of ps1 era Final Fantasy games). I overlaid a hand drawn image of my world map on a terrain in unity, and I raised the terrain for the continents to an even level so I have continents and then the lower water level. I can continue to do this for the hills and mountains as well, but I'm not entirely sure I'm going about this the right way. Like, how do I do the water? How do I make the forested areas? It seems like shaders might play a part here but I'm not very well versed in that area. Any help or tutorial recommendations, even just good things to search for or general tips will be a big help! Thank you!
