# NeoBiosphere<\/p>\n
A Biosphere world generation mod for NeoForge 1.21.1.<\/p>\n
NeoBiosphere generates large grid-aligned spheres in the Overworld (with an optional upper-hemisphere mode) while preserving vanilla biome sampling behavior. This allows different climate zones and terrain styles to appear naturally across different spheres. You can fine-tune sphere size, spacing, center height, bridge behavior, and more through configuration.<\/p>\n
## Highlights<\/p>\n
– Sphere-based Overworld generation with a clean grid layout.
\n– Multi-biome support based on vanilla noise biome sampling.
\n– Highly configurable parameters: radius, spacing, center Y, sphere block, bridge options, and more.
\n– Per-sphere variety: each sphere gets a random size and block type from configurable lists, while remaining deterministic across world reloads.
\n– Optional upper-hemisphere mode for sky-island or challenge-style gameplay.
\n– Automatic sphere-to-sphere bridges for smoother exploration.
\n– Compatibility-oriented implementation via Biome Modifier and noise routing integration.<\/p>\n
## Requirements<\/p>\n
– Minecraft: 1.21.1
\n– NeoForge: 21.1.216+
\n– Java: 21<\/p>\n
## Installation<\/p>\n
1. Install NeoForge for Minecraft 1.21.1.
\n2. Put the mod jar into your `mods` folder.
\n3. Launch the game and create a new world.<\/p>\n
Using a fresh world is strongly recommended to avoid broken borders with previously generated chunks.<\/p>\n
## Configuration<\/p>\n
Config file path in development environment: `run\/config\/NeoBiosphere.toml`<\/p>\n
Typical path in normal client\/server installations: ` ### Main Settings<\/p>\n “`toml – `radius`: Maximum sphere radius. ### Tuning Notes<\/p>\n – Overlap behavior depends on `spacing` versus `2 * radius`. ### 3. Why are spheres different sizes or using different blocks?<\/p>\n This is expected when `min_radius < radius` or when `sphere_block` contains multiple entries. Each sphere deterministically picks its own size and block type based on its grid coordinates, so reloading the world always produces the same sphere layout.\n\n### 4. Why is the sphere shell block not applied?\n\nMake sure each block ID in the list is valid, for example `minecraft:glass`. Invalid IDs can cause config load failure or fallback behavior. If using a single block type, the list must still be formatted as `[\"minecraft:glass\"]`.\n\n### 5. What should I do if another terrain mod conflicts?\n\nFirst check whether both mods modify Overworld noise settings or Carver flow. In heavy conflicts, keep only one primary world-shape mod.\n\n## License\n\nGNU General Public License v3.0\n\n## Feedback\n\nIssue tracker:\n\n- https:\/\/github.com\/mlus-asuka\/NeoBiosphere\/issues\n\n<\/p>\n","protected":false},"excerpt":{"rendered":" Generate world as sphere with different biomes<\/p>\n","protected":false},"featured_media":109473,"template":"","meta":{"_minecraft_slug":"neobiosphere","_minecraft_project_id":"qKyR65TX","_minecraft_author":"mlus","_minecraft_license":"GPL-3.0-only","_minecraft_downloads":215,"_minecraft_follows":3,"_minecraft_client_side":"unsupported","_minecraft_server_side":"required","_minecraft_storage_type":"zip","_minecraft_archive_name":"neobiosphere.zip","_minecraft_size_bytes":1949616,"_minecraft_version_count":7,"_minecraft_updated_at":"2026-05-16T18:40:36.299454Z","_minecraft_date_created":"2025-12-14T21:56:09.693381Z","_minecraft_date_modified":"2026-05-12T10:44:19.922044Z","_minecraft_project_url":"https:\/\/modrinth.com\/mod\/neobiosphere","_minecraft_icon_attachment_id":109473,"_minecraft_imported_at":"2026-06-06T10:28:49+00:00","_minecraft_import_hash":"9f2e1faa1f2c0ec350553ba73afe34ab","_minecraft_versions":"","_minecraft_links":"","_minecraft_gallery":"","_minecraft_api_metadata":""},"mod_category":[158,159],"mod_loader":[160],"minecraft_version":[37],"class_list":["post-109472","mod","type-mod","status-publish","has-post-thumbnail","hentry","mod_category-neoforge","mod_category-worldgen","mod_loader-neoforge","minecraft_version-1-21-1"],"yoast_head":"\n

\n– `min_radius`: Minimum sphere radius. Set equal to `radius` for fixed-size spheres; set lower to enable per-sphere random sizing.
\n– `spacing`: Distance between sphere center points on the grid.
\n– `center_y`: Y level of sphere centers.
\n– `sphere_block`: List of block IDs used for sphere shells. Each sphere randomly picks one type from the list, deterministically based on its grid position. For example `[“minecraft:glass”, “minecraft:stone”, “minecraft:obsidian”]`.
\n– `only_upper_hemisphere`: Generate only upper hemispheres when enabled.
\n– `generate_bridge`: Enable or disable bridges between adjacent spheres.
\n– `bridge_block`: Block used for bridges.
\n– `bridge_radius`: Bridge radius (larger values make thicker bridges).<\/p>\n
\n– If `spacing > 2 * radius`, spheres have gaps between them.
\n– If `spacing = 2 * radius`, spheres are tangent.
\n– If `spacing < 2 * radius`, spheres overlap.\n\nSuggested presets:\n\n- Classic style: `radius=128, min_radius=128, spacing=500, center_y=62`\n- Compact exploration: `radius=160, min_radius=160, spacing=320, center_y=70`\n- Challenge mode: `only_upper_hemisphere=true, generate_bridge=true`\n- Varied spheres: `radius=180, min_radius=80, sphere_block=[\"minecraft:glass\", \"minecraft:stone\", \"minecraft:obsidian\"]`\n\n## Compatibility\n\nNeoBiosphere is designed to support most terrain\/ecology mod setups, but world generation is a high-conflict area. Please note:\n\n- Usually compatible with:\n - Mods that mainly add mobs, vegetation, structures, or surface features.\n - Mods that append content through Biome Modifiers.\n\n- Potential conflicts with:\n - Mods or datapacks that directly replace noise settings for `minecraft:overworld`, `minecraft:large_biomes`, or `minecraft:amplified`.\n - Mods that deeply alter Carver, Aquifer, or ChunkGenerator pipelines.\n\n- Recommended approach:\n - Treat NeoBiosphere as the primary world-shape mod.\n - Test in a fresh world before finalizing load order and datapack priority in modpacks.\n\n## Covered Overworld Noise Presets\n\nCurrent version includes support for these Overworld presets:\n\n- `minecraft:overworld`\n- `minecraft:large_biomes`\n- `minecraft:amplified`\n\n## FAQ\n\n### 1. Why does my old world look incomplete?\n\nChanging world generation settings does not regenerate already created chunks. A new world is recommended.\n\n### 2. Why are bridges not generating?\n\nCheck the following:\n\n- `generate_bridge=true`\n- `bridge_radius >= 1`
\n– `bridge_block` is a valid block ID<\/p>\n
