Heightmap Terrain for Godot Engine 3.0
For a more recent, plugin version of this module, see https://github.com/Zylann/godot_heightmap_native_plugin
C++ module for creating heightmaps.
Install the contents of the repo in a folder under "modules/", named "hterrain".
IMPORTANT: if you clone the repo, Git will create the folder as the repo name, "godot_heightmap_terrain". But because Godot SCons scripts consider the folder name as the module's name, it will generate wrong function calls, so you must rename the folder "hterrain".
