GlymeraSchematic - Bring Your Minecraft Builds to Hytale

Missing your Minecraft home? Bring it to Hytale! GlymeraSchematic imports .schem, .litematic and legacy .schematic files straight into your Hytale world — 1595 block mappings, correct orientation, zero drops on place, and mega-builds stream in without freezing your server.

What is GlymeraSchematic?

You've spent hundreds of hours building your dream castle, village, cathedral or gothic skyscraper in Minecraft, and now you're moving to Hytale. GlymeraSchematic loads any Minecraft schematic file, translates every block into its closest Hytale counterpart, and places the entire structure into your world with a single command — no manual block-by-block copying, no broken orientations, no chunks full of random stone.

Whether you grabbed a build off Planet Minecraft, exported your own world with Litematica, or pulled a .schem out of FastAsyncWorldEdit, it works.

How It Works

1. Drop the file in the imports folder

Put any of these formats into plugins/GlymeraSchematic/imports/:

• .schem (Sponge v1 / v2 / v3) — the modern WorldEdit / FAWE format
• .litematic (Litematica mod export)
• .schematic (legacy pre-1.13 format — see note below)

2. Stand where you want it

Fly or walk to the position where you want the bottom-north-west corner of the structure to end up.

3. Import

/gsch import <filename>

The plugin resolves all blocks through the bundled mapping table, places them in two smart passes (stable blocks first, fragile ones like torches and plants second, so nothing drops), and confirms how many blocks were placed.

Optional rotation: /gsch import <filename> N|E|S|W rotates the whole build 0/90/180/270 degrees.

4. Change your mind?

/gsch undo

Restores the area to exactly how it was before the last import, block by block, with correct rotations.

Features

• 1595 block mappings covering essentially all Minecraft 1.21.6 blocks — stones, woods, metals, glass, wool/concrete, plants, crops, leaves, stairs, slabs, walls, fences, doors, trapdoors, signs, banners, carpets, copper variants, sculk, froglights, mushrooms, pottery, heads, and more
• Proper block orientation — stairs point the right way, doors open on the correct hinge, walls connect to neighbours, trapdoors hang on the right side, furnaces face forward, chests face the player-side
• Zero drops during import — two-pass placement puts all support-providing blocks down first, then the fragile ones (plants, torches, rails, buttons, pressure plates, signs, beds, ...). No flowers fall, no torches pop.
• No mining lag afterwards — every imported block is marked as "deco" and receives a full block-update pass, so connection state, lighting and block-entity data are fully initialised from the start
• Tree-decay immunity — log floors, wood beams and artistic log sculptures stay put even if they're nowhere near a natural tree
• Building-stability — neighbours of a block you mine out don't collapse; the deco marker survives on the remaining imported blocks
• Schematic integrity preserved — what was symmetrical in Minecraft stays symmetrical in Hytale
• Unknown blocks become air, never visible stone placeholders, so your grass fields stay grassy
• Rotation support at import time — pick which cardinal direction the build faces in the world
• Undo — full per-block snapshot-based rollback after any import
• Mega-build streaming (new in 3.0) — large imports are placed in batches across ticks instead of one giant operation, so the server stays responsive while a cathedral materialises. Progress messages at 25/50/75%, and /gsch cancel aborts mid-import with a full rollback
• Configurable size limit (new in 3.0) — the 2-million-cell cap is now just a config default; raise maxBlocks in config.json and import multi-million-block cities
• No asset pack required — everything ships in the single JAR

Commands

All commands are OP-only. Prefix is /gsch.

Supported Formats

Configuration

Block mapping — plugins/GlymeraSchematic/mapping.json (created on first start)

This is the complete Minecraft → Hytale block translation table, 1595 entries. Edit any mapping to re-route specific blocks (e.g. prefer Wood_Redwood_Planks instead of Wood_Goldenwood_Planks for oak_planks on your server), then /gsch reload to apply without restarting.

Blocks not in the table are placed as air — which keeps unknown / modded blocks from producing random stone artefacts.

Limits & streaming — plugins/GlymeraSchematic/config.json (created on first start)

/gsch reload applies config changes live — no server restart needed.

One thing to keep in mind when raising maxBlocks: the undo snapshot lives in memory (~40 bytes per placed block, so a 10-million-block import holds roughly 400 MB until the next import or restart). Give your server the RAM to match your ambitions.

Installation

1. Place GlymeraSchematic-3.0.0.jar in your server's mods/ folder.
2. Start (or restart) the server.
3. Drop schematic files into plugins/GlymeraSchematic/imports/.
4. /gsch import <filename>.

No external asset pack, no manifest tweaking, no Hytale version lock — the plugin declares ServerVersion: "*" and works with any current build.

Good to Know

• The plugin uses a family-specific rotation calibration per block type (stairs / trapdoors / doors / chests / walls / fences all have slightly different render defaults in Hytale — the plugin applies the correct offset per family)
• Walls/fences/panes reconstruct their connection axis from the source schematic's connection properties (north/south/east/west = none/low/tall or true/false), so T-junctions and L-corners come out right
• Hytale has no built-in corner-stair variants; MC's shape=inner_left/outer_right etc. are rendered as straight stairs. Visible but generally acceptable
• Hytale logs have no axis property, so Minecraft log-orientations (horizontal logs, pillars) collapse to upright. Use Hytale's own beams / decorative wood variants for horizontal runs
• Banners, candle cakes, hanging signs and a few redstone-internal blocks are intentionally skipped (placed as air) because there is no reasonable Hytale equivalent
