Hello,
I’d like to use heightmap for landscape. My question - is it necessary that heightmap dimension and its texture are the same. FOr insatnce, if heightmap is 6464 points, the texture is also 6464?
Nope. You can apply any texture size to the heightmap, in both terrain engines.
Note, however, that if you’re using the GeoMipTerrain, 64x64 is not a valid size for the heightfield. You need to have a power-of-two-plus-one, such as 65x65.
The texture, on the other hand, its best to make that a normal power-of-two, such as 64x64.
