TerraSame you are wrong i use two terrains in my level the first is just a normal 250*250 terrain and i deform the second (250*250) with an hightmap and the hight of the first terrain...
ok 250*250 isnt bigger then 64000(the maximum), but it worked fine with 500*500,too.
but if you terrain is to big(ca. 60*60-500*500) i would do that what TerraSame says. but watch out - you can easyly run into nexus problems with this metod.
so if you only want to deform your terrain while loading/starting use one big terrain, but if you want to make realtime-deformations use much small terrains
