Gta 5's terrain is made up of models

[Vida Marcell]

This is what i found, the terrain is not based on a heightmap, its based on sere val meshes.

[Genebris]

Heightmap is just a method to define a mesh

[Josh]

Wow, brute force.

The height map is only the definition of a representative terrain grid.  If the height map is of a single color, black, the terrain is created flat with a certain number of polygons that are not usually many compared to a height map that presents different slopes in a terrain.
