Heightmap terrain 1.6.1 3D Tools 3.3 Community

Submitted by user Zylann; MIT; 2024-10-09

Heightmap-based terrain for Godot 3.3.
It supports collision, texture painting, colouring, holes, level of detail, and grass.
WARNING: this version is no longer maintained, and might not work out of the box in Godot versions past 3.3, in which case you will have to fix it yourself. The version available for Godot 4 has had more updates.

Fixes in 1.6.1:

- Fixed static typing error in terrain importer dialog (thanks to McSpider)

Changes in 1.6:

- Added island modifier to the terrain generator
- Added option to add the current heightmap to the generated one in the generator
- Added `render_layers` property to expose the same as `VisualInstance.layers`
- Added `anisotropic` parameter to packed texture importers
- Added support for loading terrain maps imported as `Image`, allowing modification in game
- Added basic support for pen pressure (tablets)
- Added random brush rotation
- Added brush multi-shape randomization
- Added brush spacing based on time and distance
- Added support for importing `.xyz` files as heightmap
- Added rotation and centering support
- Increased brush size slider maximum to 500, and allow up to 4000 if typed in (expensive, use at your own risk)
- Ported quad tree code to GDNative for a bit of speedup on Windows and Linux (thanks to tinmanjuggernaut)
- Prefixed ALL internal classes of the plugin to prevent clashes with `class_name` (see issue #313)
- Added workarounds to allow the plugin to initialize even if assets are not imported yet (The UI might still have issues, in this case you need to restart Godot)
- Dropped support for Godot 3.1 and 3.2 due to engine crashes.
- Fixed grass chunks not updating properly when the terrain is moved
- Fixed invalid index error that can happen in some cases in the TextureArray importer mode
- Fixed loading an existing texture array when the current texture set is empty
- Fixed `BaseButton.focus_mode` warning printed when the plugin is enabled
- Fixed some dialogs going outside window if editor font is larger (buttons outside windows did nothing)
- Fixed flatten brush not allowing to set decimal heights
- Fixed wrong shading in `multisplat16` shaders
