GlymeraPrefab - Spawn Any Structure!

Place any of Hytale's 7800+ prefab structures anywhere in your world with a simple command.

What is GlymeraPrefab?

GlymeraPrefab gives server operators instant access to every prefab structure in Hytale - from tiny rock formations to massive Kweebec villages. Search, browse, and spawn structures by number. Full undo support restores the original terrain including fluids.

7800+ prefabs across all categories: Settlements, Dungeons, Monuments, Caves, Trees, Rock Formations, and more.

How It Works

Browse & Search

/gps list [page]          - Browse all prefabs (20 per page)
/gps search <text>        - Search by name
/gps search <text> <minKB> - Filter by minimum file size (KB)
/gps info <nr>            - Show prefab details (size, anchor, dimensions)

Spawn & Undo

/gps spawn <nr> [N/E/S/W] - Spawn prefab at your position
/gps undo                  - Remove last spawned structure, restore terrain

Reload

/gps reload               - Rescan prefab list (picks up new asset packs)

Features

Numbered List

All prefabs are sorted alphabetically and numbered. Search for what you want, note the number, spawn it. No need to type long dot-notation paths.

Size Filter

The search command accepts an optional minimum file size in KB:
- /gps search kweebec - All 337 Kweebec prefabs
- /gps search kweebec 50 - Only prefabs > 50 KB (houses, shops, towers)
- /gps search kweebec 1000 - Only prefabs > 1 MB (camps, villages)

This filters out small decorative elements (garden patches, lampposts) and shows only substantial structures.

Automatic Ground Alignment

Structures are automatically placed so their bottom aligns with your feet. Stand on flat ground, spawn a structure, and its foundation sits right where you are.

Rotation

Spawn structures facing any direction:
- N - North (default)
- E - East
- S - South
- W - West

Recursive Child Resolution

Large layout prefabs (villages, camps) contain PrefabSpawner blocks that reference sub-structures. GlymeraPrefab automatically resolves and places all child prefabs, so settlements spawn complete with all their buildings, shops, guard towers, and decorations.

Full Undo with Terrain Restore

Every spawn creates a block-level snapshot of the original terrain (including fluids). Use /gps undo to perfectly restore the landscape. No holes, no leftover water.

Auto-Discovery

The plugin scans all asset packs at startup. New mods or asset packs are automatically picked up on /gps reload or server restart.

Prefab Categories

Installation

1. Place GlymeraPrefab-1.0.0.jar in your server's mods/ folder
2. Start (or restart) the server
3. Done! No config file, no asset pack needed.

Commands Reference

All commands are OP-only.

Good to Know

• OP-only - All commands require operator permissions
• No NPCs - Structures spawn without entities (buildings only, no NPC crowds)
• Undo is per-player - Each player can undo their own last spawn
• Undo stores one level - Spawning a new structure replaces the previous undo snapshot
• Large structures may take a moment - A village with 40+ sub-prefabs needs a second to fully resolve
• Minor edge cases - Decorative blocks (mushrooms, grass) that Hytale generates automatically after placement may not be captured by undo
• Numbers change on reload - Prefab numbers are assigned alphabetically and may shift when new prefabs are added

Performance

GlymeraPrefab is lightweight:
- No background tasks - Only active when a command is used
- Cached prefab buffers - Hytale's built-in cache prevents redundant file reads
- Lazy loading - Prefab data is only loaded when spawning or viewing info
- File-system scan at startup takes < 1 second for 7800+ prefabs
