GlymeraFloatingIslands - Sky Islands for Hytale
Create new worlds made entirely of floating islands — Minecraft-style. Choose a theme or let each zone keep its native biome.
Most actual version only working for Hytale stable 5 !
What is GlymeraFloatingIslands?
GlymeraFloatingIslands adds floating sky islands worlds to your server. Each world consists purely of islands suspended in the air — no ground, no ocean, no caves. The islands are generated natively by Hytale's terrain pipeline, so they come with grass, flowers, trees, structures, NPCs and mobs out of the box, exactly as they would on a normal map.
You pick a biome preset when you create a world, and every island in that world is built from the preset's blocks. Or you go with the native preset and let each zone keep its own biome — so a single world has sand islands in desert zones, snow islands in tundras, grass islands in plains, and so on.
Works out of the box — one command to create, one to teleport. No client mod needed.
Quick Start
/fi biomes — Show available biome presets
/fi create sky native — Create a new floating-islands world named "sky"
/fi tp sky — Teleport to it
/fi back — Return to your previous world
That's it. The world is generated, saved, and persists across server restarts.
Biome Presets
Every preset places native covers (grass, flowers, trees), structures (Hytale Unique-Prefabs) and NPC spawns on the islands.
Commands
/fi create <n> <biome> — Create a new floating-islands world (OP)
/fi tp <n> — Teleport to a managed world (OP)
/fi back — Return to the previous world (OP)
/fi list — List all floating-islands worlds (everyone)
/fi biomes — Show all available biome presets (everyone)
/fi delete <n> — Delete a world (folder + config, no restart needed) (OP)
/fi reload — Reload the config and re-apply per-world settings (OP)
/fi delete cleanly unloads the world, deletes its disk folder, and removes it from the config — all in one step. No server restart, no manual cleanup.
Features
Configuration
Every world gets an entry in plugins/GlymeraFloatingIslands/config.json. Defaults come from the preset. You can override any value and reload with /fi reload:
Good to Know
Installation
1. Place GlymeraFloatingIslands.jar in your server's mods/ folder
2. Start (or restart) the server
3. Done!

Biome Presets
- native — Per-zone mixed biomes (sand in deserts, snow in tundras, grass in plains)
- grasslands — Classic green Minecraft-style islands
- desert — Warm sandy islands
- snow — Frozen arctic islands
- volcanic — Dark basalt floating rocks
- crystal — Pale crystalline islands
Every preset places native covers (grass, flowers, trees), structures (Hytale Unique-Prefabs) and NPC spawns on the islands.

Features
- Native Hytale world generation — islands use the real biome pipeline, so vegetation, trees, structures, and mobs all spawn naturally
- 3D Simplex noise islands — organic cave-like shapes, not blocky
- Vertical taper — soft edges top and bottom, no flat cutoffs
- Guaranteed spawn platform at world origin so you never fall into the void
- Configurable per world — island size, density, Y-range, custom block choices
- Event-driven biome application — works even for pre-existing worlds and across restarts
- No caves — stalactites that would dangle in empty sky are disabled per world
- No water — empty sky worlds don't generate oceans between islands
- Bounded prefab placement — structures only spawn within the island Y-range
- Chunk post-processor — clears any block outside the island range automatically
Configuration
Every world gets an entry in plugins/GlymeraFloatingIslands/config.json. Defaults come from the preset. You can override any value and reload with /fi reload:
- islandSize — Noise scale. Smaller = bigger islands. Range: 0.005-0.05
- density — Fraction of Y-range that becomes solid. 0.1 = sparse, 0.3 = minecraft-like, 0.5 = dense
- heightMin / heightMax — Lowest / highest Y coordinate for islands
- surfaceDepth — Thickness of the surface-block layer
- surfaceBlock / subBlock / coreBlock — The three layers of each island
- native — Set to true to inherit the zone's native biome instead of custom blocks
Good to Know
- The plugin only modifies terrain for worlds it manages — your existing default world is untouched
- NPCs may spawn over open sky and fall off islands — Hytale's spawning system is zone-wide
- Player-built structures below heightMin or above heightMax do not persist across chunk cycles — build on the islands themselves
- Plugin runs silently — no log output in normal operation
- No asset pack needed — the JAR is around 30 KB
Installation
1. Place GlymeraFloatingIslands.jar in your server's mods/ folder
2. Start (or restart) the server
3. Done!
