Connected Biomes

🌄 Connected Biomes

Tired of biomes that end in a perfectly straight wall? Connected Biomes makes borders between biomes flow into each other naturally, then softens the blocky terrain with partial-height tiles and optional rounded ground.

🌿 Natural Biome Transitions

• Biome borders are warped by noise into fingers, islands and gradual blends instead of hard lines
• Vegetation bleed: trees and plants from a compatible neighbour sparsely cross the border, so a forest fades into the plains instead of stopping
• Adjustable transition width, blending intensity and noise scale
• Smart compatibility reads modded biomes’ data (climate, tags, trees) to decide how they should blend, so it works with worldgen mods out of the box
• Blacklist any mod or single biome (modid or modid:biome) to keep its vanilla borders

🧱 Terrain Tiles

One-block height steps are smoothed during world generation with partial-height tiles: blocks split into 2, 4 or 8 layers (your choice).

23 tile types: grass, dirt, coarse dirt, rooted dirt, podzol, mycelium, moss, mud, clay, sand, red sand, gravel, snow, stone, deepslate, granite, diorite, andesite, tuff, calcite, sandstone, red sandstone and terracotta.

• Tiles behave like their parent block: grass spreads, sand and gravel fall
• Choose whether a mined tile drops a full block or a proportional amount

🔵 Rounded Terrain (experimental, visual only)

• Rounded tiles: smooth tile surfaces (collision stays stepped)
• Round edges: soften exposed corners of tiles and snow
• Rounded Blocks: ground next to tiles is rounded along with them
• Every Block Rounded: round all the ground in the world
• Full rounding: no edges or corners left at all, with curved surfaces
• Trees, leaves, crafting tables and builds are never touched
• Applies instantly, even in existing worlds

🎥 Smooth Step Camera

Your camera glides up steps, tiles and rounded terrain instead of snapping.

⚙️ Configuration

❓ FAQ

Can I use it in modpacks? Yes! It’s MIT-licensed. A link back is appreciated.
Does it work with other worldgen mods? Yes, that’s what Smart compatibility is for. If a biome looks wrong, add it to the blacklist and report it.
