Known Issues

World scale configuration on 1.20.1: Changing the world scale is currently not supported on Minecraft 1.20.1.

Note

This is a preview release so some bugs or unexpected behavior may still occur. Please report any issues you encounter.

v2.2.0

Added

• Spawn on land: The world spawn point is now automatically placed on land. The search radius is configurable via spawn_search.initial_size and spawn_search.max_size in terrain-diffusion-mc.properties.
• CPU build uses CoreML on MacOS: On the CPU build, the mod attempts to use Apple Silicon GPUs via CoreML, if available.

Fixed

• Sinytra Connector compatibility: Improved compatibility with Sinytra on 1.21.1
• Deepslate generation: Deepslate now generates correctly underground.

Performance

• Faster chunk generation: Improved chunk generation speed.

What's Changed

• 3 build options now provided: DirectML (Windows), CUDA (Any NVIDIA GPU), CPU
• 1.21.1 support added
• Logs have been cleaned up

Contributors

• @batata1-jg for DML support
• @ThatDamnWittyWhizHard for 1.21.1 support

Bug fixes:

• Fixed the sun not moving
• Fixed the sky disappearing

• Reverted to ONNX runtime 1.20.0, since 1.21.0 has issues with some older JVMs
• Improved robustness of the model loading pipeline, particularly for cached optimized models.

Downloading models on first launch to reduce jar size.

Fully self-contained version. Requires CUDA (12.x) and cuDNN (9.x), or can be used with CPU.
Not compatible with worlds made with v1.x.x.

Compatible Minecraft version is indicated after the + in the jar file.

For Minecraft v1.21.10

Changelog: Support new API, adding more config options

Old configs will need to be updated.

New config default:

# Terrain Diffusion MC configuration

# This is the native resolution for height conversion (Resolution before `scale` is applied)
# If you are using a 30m resolution model, this should be 30 for real life slopes.
# You can adjust the value down to increase terrain height or up to decrease it.
height_converter.resolution=30

# Scale factor for terrain upsampling. 1 = 1 block per API pixel, 2 = 2 blocks per API pixel, 4 = 4 blocks per API pixel, etc.
# Example: If you are using a 30m resolution API, then 1 = 30m resolution, 2 = 15m resolution, 4 = 7.5m resolution, etc.
heightmap_api.scale=2

# Noise scale factor for terrain at large slopes (default: 1.0)
# mainly affects how "rough" cliffs or steep slopes are
heightmap_api.noise=1.0

# Base URL of the heightmap API server.
heightmap_api.url=http://localhost:8000

# ADVANCED
# Gamma and c of terrain (Mod applies elev -> ((elev + c)^gamma - c^gamma) before scaling down by `height_converter.resolution`)
# I tried experimenting with this to boost low-elevation relief, but didn't really see any improvements. Maybe I missed something. Note that this changes the scale of the elevation, so `height_converter.resolution`
# will need to be changed accordingly (usually to a much smaller value).
height_converter.gamma=1.0
height_converter.c=30.0

For Minecraft 1.21.10

Changelog:

• Increased build height to 640
• Limited API cache size plus reset on world creation
• Added API URL to config
