Terrain3D

An editable terrain system for Godot 4, written in C++.

Features

• Written in C++ as a Godot gdextension plugin, which works with official engine builds
• Geometric Clipmap mesh terrain (as used in The Witcher 3)
• Up to 16k x 16k, sliced up in non-contiguous 1k regions (think multiple islands without paying for 16k^2 vram)
• Up to 10 levels of detail (LODs)
• Up to 32 textures
• Sculpting, texture painting, texture detiling, paint colors or wetness
• Supports importing heightmaps from HTerrain, WorldMachine, Unity, Unreal and any tool that can export a heightmap (raw/r16/exr/+)

See the Wiki for more details on project status, features, design, and usage.

Requirements

• Supports Godot 4.0+
• It is being developed on Windows. It should work on Windows, Linux, and OSX if you build it yourself.

Installation & Setup

1. Download the latest release, or build the plugin from source.
2. Close Godot, then Copy addons/terrain_3d to your project folder in addons/terrain_3d.
3. Open Godot. Let it complain about importing errors and may even crash. Then restart Godot.
4. In Project Settings / Plugins, ensure that Terrain3D is enabled.
5. Open the demo scene demo/Demo.tscn, or:
6. Create or open a scene and add a new Terrain3D node.
7. Select Terrain3D. In the inspector, create a new Terrain3DStorage resource.
8. Click the down arrow to the right of the storage resource and save it as a binary .res file. This is optional, but highly recommended. Otherwise it will save terrain data as text in the current scene file.
