What Tectonic-Horizon does.
Unofficial native Rust port of Tectonic 3.0.1 by Apollo (Apollounknowndev), revision 0761b561062de01b701d2571401f625c31059a9a under CC0-1.0. Not made or endorsed by Apollo or the Horizon project.
Mountain ranges, terrain density recipes, underground rivers and configurable terrain for Horizon 26.3. Source-only native mod: install in the launcher, then Build; runs with the game's account permissions. No Minecraft code or assets are included.
Enable under Options > Mods before opening a world. The mod's Settings page edits terrain and biome configuration. Config: config/tectonic-horizon.json in the game home. Invalid configuration logs a diagnostic and uses defaults. Restart after editing; new chunks only. Select increased height before world creation.
Pins upstream Horizon 8dbbde43501924d16497d251e6e9d08f812eafcd and Mixins e8cd0aa38cffef49cb2e088ef716baa107148c02. See docs/REVIEW-0.3.4.md for current validation and docs/VALIDATION.md for historical checks with their original revisions.
No block-for-block Java parity claim. Native river-decoration placement differs from Lithostitched. Java config UI and Terralith/CliffTree overlays are omitted. Other biome mods need their own Horizon ports.
Author-supplied screenshot captured November 1 in our Horizon fork; illustrative, not evidence of current upstream validation. Minimap is a separate mod. Original Tectonic by Apollo; Horizon adaptation by eltanschauung with Codex assistance. Source licenses, notices and provenance hashes retained.
