GlymeraSchematic v2.0

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.

Most actual version only working for Hytale stable 5 !

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. No flowers fall, no torches pop
• No mining lag afterwards — every imported block is marked as "deco" and receives a full block-update pass
• 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
• Schematic integrity preserved — what was symmetrical in Minecraft stays symmetrical in Hytale
• Unknown blocks become air, never visible stone placeholders
• Rotation support at import time — pick which cardinal direction the build faces
• Undo — full per-block snapshot-based rollback after any import
• No asset pack required — everything ships in the single JAR

Commands

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

/gsch list — List every schematic file currently in the imports folder
/gsch info <filename> — Show dimensions, block count and palette size of a schematic
/gsch import <filename> [N|E|S|W] — Import at your position, optional rotation
/gsch undo — Roll back the most recent import
/gsch reload — Re-read the mapping file after editing
/gsch read — Inspect the block under / next to you (ID, rotation, yaw/pitch/roll) — handy for debugging mappings
/gsch test — Place a small test volume around you (developer tool)
/gsch teststairs — Place eight straight stairs in all four directions to verify rotation
/gsch calibrate — Place calibration blocks to verify Hytale's yaw convention

Supported Formats

• Sponge Schematic v1 / v2 / v3 (.schem) — Full support. Block-state properties (facing, half, shape, connections, ...) parsed completely
• Litematica (.litematic) — Full support. Same internal format as Sponge, identical fidelity
• Legacy Minecraft Schematic pre-1.13 (.schematic) — Block types yes, orientations no. The legacy format stores data values numerically, without block-state strings. For orientation-sensitive builds, use a converter (WorldEdit, Litematica) to upgrade to .schem or .litematic first

Configuration

File at plugins/GlymeraSchematic/mapping.json (created on first start). This is the complete Minecraft to Hytale block translation table, 1595 entries. Edit any mapping to re-route specific blocks, 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.

Maximum import size: 2,000,000 block cells per command (approx 126x126x126). For larger builds, split them in your schematic editor first.

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)
• Walls/fences/panes reconstruct their connection axis from the source schematic's connection properties, 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

Installation

1. Place GlymeraSchematic.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.
