Am I missing something? They’re pretty small…I’d have to scale them to 2x2 (4x more surface area) what they start as before having something I consider average sized. Why are they so small? Is it possible to make them larger?
Terrains size is define by the terrain resolution, so you can just change the terrain resolution to make a bigger map, under terrain->set resolution
It’s based on a single texture, so it’s limited by the maximum texture size supported on the system that is going to run the editor/application. In general 2048x2048 is quite common, 4096 is available sometimes, and higher end cards go up to much higher sizes.
Yes, it’s under the Terrain menu.
Actually, resolution and physical size are two different things (and the density is one of the biggest factors in performance). However, they are both set by going:
Terrain → Set Resolution
In there you will see width/height/length (physical size in the Unity game space) as well as heightmap resolution.
Assuming you’re using 1 unit = 1 meter, the default is 2km x 2km, which isn’t exactly “small”. You can use multiple terrains if you need to.
