Skyroot Islands 0.5.1

This update includes all changes made since version 0.3.2.

New island families

• Added abandoned garden islands with irregular ponds, bridges, ruins, pavilions and grouped vegetation.

• Added small grove companion islands with rooted trees.

• Added weeping companion islands with taller, drooping trees.

• Added large ocean terrace islands with pools and contained waterfalls.

• Added biome-appropriate landmark trees, including conifer and savanna-style variants.

• Companion islands now vary in height, shape and placement.

• Waterfall catch islands now use irregular natural rock, moss and vegetation instead of artificial bowl-like shapes.

Improved island generation

• Improved the sides and undersides of procedural islands.

• Added displaced rock cores, eroded shoulders, fractured ridges and uneven hanging formations.

• Added several underside shape variants so islands no longer share the same lower silhouette.

• Preserved caves, ores, biome materials and playable upper surfaces.

• Added deterministic shape variation based on the world seed.

• Improved biome-aware tree selection.

• Added size tiers ranging from small islands to rare islands approximately 150 blocks wide.

• Main island height continues to vary naturally around Y=222.

• Generation remains chunk-local and avoids loading neighboring chunks.

Hanging vegetation and lighting

• Added natural cave vines and glow berries beneath procedural islands.

• Vines appear around cliffs, cavities, shelves and overhangs.

• Main strands vary from 2 to 16 blocks, with occasional strands reaching 24 blocks.

• Glow berries are spaced irregularly instead of illuminating every vine block.

• Added solid attachment, ground-clearance and biome checks.

• Vine placement remains sparse and bounded to reduce generation cost.

Rare decorated island

• Added the supplied WorldEdit island as a rare structure.

• Preserved its original scale, house, interiors, trees and decoration.

• Added three deterministic underside variants while keeping the house unchanged.

• Converted compatible modded tree materials to vanilla spruce and oak while preserving their shapes.

• Removed unsupported mod blocks and data.

• Replaced five removed blocks around the lava enclosure with vanilla blackstone.

• Removed all personal items from inventories.

• The schematic contained no saved entities.

• Added configurable generation controls:

  • decoratedIslands

  • decoratedIslandChance

  • decoratedIslandMinSpacing

• Default minimum separation between decorated islands is 1,800 blocks.

• Added /skyroot locate decorated.

New alpine island

• Added a rare, handcrafted alpine floating island.

• Features an asymmetric wooded plateau, off-center rocky mountains, grassy terraces and a winding river.

• Includes a narrow contained waterfall flowing into a separate lower rock basin.

• Added four small conifer trees around the receiving basin.

• Includes 35 conifers, irregular hanging rock formations, recesses, moss, ferns and luminous cave vines.

• Uses only vanilla Minecraft blocks.

• Can rotate in four directions while preserving its complete design.

• Added /skyroot locate alpine.

• Added configuration options:

  • alpineIslands

  • alpineIslandChance

Alpine size variations

• The alpine island can now generate at four horizontal sizes:

  • 91 blocks — 50% of selected alpine variants

  • 110 blocks — 30%

  • 130 blocks — 15%

  • 150 blocks — 5%

• The complete island scales together, including its forest, river, waterfall, vines and lower basin.

• Vertical scale remains unchanged to preserve natural proportions and safe generation height.

• The original 91-block version remains unchanged.

• The waterfall remains one block thick at larger sizes to prevent unnecessary fluid updates.

• The existing maxIslandDiameter setting limits the largest possible alpine variant.

Performance and safety

• Added bounded per-thread shape and terrain-column caching.

• Reduced repeated shape calculations during chunk generation.

• Terrain validation results are stored in a bounded cache.

• Placement only processes columns belonging to the current chunk.

• No cascading chunk loads are used.

• Island decorators do not schedule unnecessary block or fluid ticks.

• Existing blocks are protected from being overwritten by authored islands.

• Improved configuration handling and cache invalidation.

• Tightened compatibility metadata for Minecraft 1.20.1 and Forge 47.4.10.

Configuration

New family settings include:

• islandFamilies

• maxIslandDiameter

• gardenFamilyChance

• maxCompanions

• companionGap

These generation changes apply only to newly generated chunks. Existing islands and already explored terrain will not be rebuilt. Using a fresh world or exploring far beyond previously generated terrain is recommended.
