Supp guys…
So I want to create a huge terrain and I got couple of questions before starting to work on it…
First of all, I was searching forums as well as Unity Answers, I found couple of threads, but I wasn’t able to find anything useful for me…
My objective is to create a really huge terrain (“open world”)… I know I can’t handle it in one Unity terrain object, so I will have to make more of these… But here is where it starts to be complicated… I won’t make this huge terrain at once, for example I want to have countries separated by mountains, or rivers or maybe the sea (that’s not really important) so first I will create the first country and then I will work on it, you know, details… Later I will want to add another country… So I don’t want to creste the whole huge terrain at once, I want to work on it gradually…
Question #1: Can I somehow edit (Paint a texutre, edit hights) more terrains at once? Just to be sure that the borders will fit… Will have same texture and height and it will look like one terrain. I read somewhere that I can create a terrain and then divide it to 4 piecies with script… But what to do when I want to add another country…?
Question #2: Can be this achieved by exporting, editing and importing heightmaps? I have no experience with heighmaps at all…
Question #3: What about loading the terrain while playing? I read somewhere (yeah yeah again) that Unity loads only visible terrain, or I can use Occlusion Culling (I know it’s only in Unity Pro) will this be enough? Of course I will have to script loading and disabling static game objects…
If you have better idease you can always tell me and of course thanks everyone.
