I was reading this unity blog post ( https://blog.unity.com/games/experience-the-new-unity-terrain-demo-scenes-for-hdrp-and-urp ) about the terrain demo using HDRP and URP. They said they created 4x4 tiles at 4000 units at scale. But wouldn't that be 1,000 tiles? I'm creating an open world exploration game with a main island surrounded by smaller ones. I would like the main island to be roughly 3 square miles. But if I create that using 4x4 tiles, that's a lot of tiles. Would that be the preferred way? Or should I just use larger tiles?
