Dynamic modification of landscape heightmap?

Hi,

I’d like to create a dynamic landscape, where the terrain would morph depending on the camera position.

Ideally, I’d like to blend multiple pre-existing heightmaps, so different sections of the terrain would be modulated.

Is it possible to dynamically load and modify terrain heightmaps (or even directly vertices)?

Thx !

How did it go? I am looking for similar solutions right now.
