Changes
Preset Editor & UI
- Redesigned the preset selector with landscape cards, a dark theme, preset summaries, and responsive previews.
- Added live interactive voxel previews in real time.
- Added setting search by name, description, and group (
Ctrl+F), modified-setting filters, andCtrl+Ssaving. - Separated library browsing from active drafts: arrow navigation no longer overwrites unsaved edits.
- Added confirmation prompts for discarding drafts, resetting settings, and deleting presets.
- Added JSON formatting, draft persistence across window resizing, and scrollbars for smaller displays.
- Expanded full-screen world overview with terrain, height, and climate modes, including point-centered zoom.
Terrain Generation & Biomes
- Added separate NeoForge and Fabric builds for Minecraft 1.21.1 (requires Java 21 and Architectury API; Fabric also requires Fabric API).
- Mountain height, width, and steepness settings now fully scale generation, enabling taller and more varied ranges.
- Added smooth transitions between foothills and adjacent regions.
- Added configurable ocean-island relief featuring underwater shelves and elevated centers.
- Softened river and lake banks, and improved eroded badlands terrain.
- Rebalanced forest density and removed unintended bare patches across dry river valleys.
- Fixed alignment and placement boundaries for deserts, cold lakes, rivers, and oceans.
Rivers & Lakes
- Improved transitions along lakeshores and coastal borders.
- Fixed riverbed striping artifacts across lakes by carving river paths before resolving lake basins.
- Aligned connecting channel water levels directly with the lake surface.
- Added lake-outlet validation: basins only carve down when a valid downhill drainage path exists.
Caves & Structures
- Rebalanced aquifers with bounded local water pockets.
- Added targeted structural foundation supports beneath village buildings and paths crossing open cave mouths.
- Extended river channel clearance protections to surface structures.
- Prevented surface lava pools from igniting unintended fires.
Compatibility & Fixes
- Streams Reflowing: Fixed the NeoForge crash when dispatching stream network packets.
- Known Issues:
- No connection between rivers and lakes.
- Increased delay during initial world load when paired with Streams Reflowing 2.13.1 or Spawn 4.0.7.
Projects on Modrinth are automatically available through a Maven repository for use with JVM build tools such as Gradle. To learn more about the Modrinth Maven API, click here.
Note: When available, you should use the creator's maven repo instead as it will have transitive dependency information that the Modrinth Maven API does not. You may also end up with duplicate dependencies if you use a mix of Modrinth and non-Modrinth Maven repositories for your dependencies, because the group identifier will be different when served through the Modrinth Maven API.
