Why it’s here
Godot teams can iterate terrain from small scenes to worlds spanning tens of kilometers and import heightmaps produced by Gaea, World Machine, Unity, and related tools.
Best fit
Art, animation, audio, levels, and narrative turn mechanics into a believable world.

Before you commit
It is coupled to Godot 4 and specific add-on versions, so read migration notes before upgrading; very large worlds still need explicit CPU, GPU, memory, collision, navigation, shader, and foliage budgets.
