How to Safely Share Modded Map Seeds for Hytale and Arc Raiders

Stop wasting time on bad packs: how to safely package, document and torrent Hytale darkwood worlds and Arc Raiders maps in 2026

Hook: You’ve found a beautiful Hytale darkwood biome or built a tight Arc Raiders arena, but when you share it people complain about broken imports, malware scares, or dead torrents. This guide fixes that — step-by-step packaging, metadata, torrenting and seeding practices tuned for 2026 so your maps install cleanly, verify fast and stay well-seeded without exposing you or users to legal or security risks.

Why this matters in 2026

Game modding and community maps exploded through 2024–2026. Embark Studios’ 2026 roadmap for Arc Raiders promises multiple new maps, and Hytale still sees thriving community worlds built around rare assets like darkwood cedar forests. That means more creators will package and share world files — and more users will download them. Yet as trackers and clients change policies and studios tighten IP controls, sloppy releases create user friction, broken installs and security problems.

This guide assumes you plan to distribute only content you have the right to share (your own maps, or assets redistributed with permission). It focuses on practical steps: clean packaging, clear metadata, safe torrent creation, verification, seeding best practices and privacy guidance.

At-a-glance checklist

• Package files with a reproducible folder structure and README
• Include checksums (SHA256) and a changelog
• Sign the release with PGP when possible
• Create a .torrent with appropriate piece size, trackers and optional webseeds
• Seed responsibly (initial seed, superseed, seedbox) and maintain a clear license
• Warn users: no executables, avoid including proprietary game files, give install steps

1) Prepare the world files and map assets

Organize a reproducible folder structure

Consistency matters. Use a single top-level folder that mirrors how the game expects files to be placed. Example structure for a Hytale darkwood world pack:

• Whisperfront_Cedar_Expanse_v1.2/
  • world/ (the game world file(s))
  • assets/ (custom textures, models)
  • scripts/ (non-executable import scripts, optional)
  • README.txt
  • CHANGELOG.md
  • SHA256SUMS.txt
  • Whisperfront_Cedar_Expanse_v1.2.torrent

For Arc Raiders maps, use a similar layout but adapt to the game's map import structure. Always include only the data files required to import the map; do not include game executables, licensed audio or other proprietary files.

Strip sensitive metadata and proprietary content

Before packaging, scan assets for embedded personal data, absolute paths, or proprietary headers. Remove anything that requires redistribution permission (store assets, paid DLC files). If your map relies on a paid asset, list it as a dependency rather than bundling it.

2) Create clear, minimal, machine- and human-readable metadata

Good metadata reduces user support requests and increases trust. Include both a human README and machine-friendly metadata file (YAML or JSON).

README checklist (human)

Example README.txt excerpt:

Title: Whisperfront Cedar Expanse
Version: 1.2
Author: YourName#1234 (contact@youremail.example)
Game: Hytale (client build 2026.01+)
Description: A modest cedar (darkwood) forest biome map based on Whisperfront Frontiers for creative builds.
Install: Copy the 'world' folder to Documents/Hytale/Worlds and start Hytale > Worlds > Import > select world.hworld
Dependencies: None
SHA256: see SHA256SUMS.txt
License: CC-BY-NC-SA 4.0 (no commercial redistribution without permission)
Changelog: See CHANGELOG.md
Signature: Signed by YourName (PGP key fingerprint A1B2 C3D4...)
Security Note: No executables included. Verify SHA256 and PGP signature before importing.
  

Machine metadata (optional but recommended)

Include a small metadata.json for client-side tools and indexers to parse. Fields: title, version, author_id, game, required_build, files (with size and sha256), license, signature. This helps community sites auto-index your release.

3) Create checksums and sign the release

Checksums: Generate SHA256 checksums for each file and for the archive. SHA256 is the community standard in 2026 for release verification. Place results in SHA256SUMS.txt.

Commands (cross-platform):

• Linux/macOS: sha256sum file > SHA256SUMS.txt
• Windows (PowerShell): Get-FileHash -Algorithm SHA256 .\file | Format-List

PGP signatures: If you manage a PGP key, sign SHA256SUMS.txt and README.txt. This lets users verify the release came from you. Host your public key in your profile and paste the fingerprint in the README.

4) Torrent packaging best practices (piece sizes, naming, trackers)

File vs folder torrents

Create a single torrent that points at the top-level folder. That preserves the folder structure on download and keeps metadata predictable.

Naming conventions

Use a canonical name that includes game, map name, version and year. Example:

• Hytale-Whisperfront-Cedar-Expanse_v1.2_2026
• ArcRaiders-BlueGate-NightOps_v0.9_2026

Choosing piece size (2026 guidance)

Piece size affects torrent overhead and piece rarity. General guidance:

• Files <1 GB: use 256 KB – 1 MB pieces
• 1–10 GB: use 1 MB – 4 MB pieces
• >10 GB: use 4 MB – 8 MB pieces

Aim for a total piece count in the low thousands. Very small pieces increase torrent metadata size and tracker load; huge pieces increase the chance that single corrupted pieces force re-downloads. For most map packs in 2026 (100MB–3GB) 512KB–1MB is a good balance.

Trackers, DHT and webseeds

Include a small, curated list of public trackers to help bootstrapping. In 2026, many indexers prefer magnet links with trackers and webseeds. Consider adding a webseed (HTTPS seed) if you can host an HTTP mirror — this dramatically improves download reliability for large files without many seeds.

Rules:

• If you distribute on a private tracker, do not enable DHT/PEX in the torrent file.
• For public releases, enable DHT/PEX to maximize discovery.
• Avoid trackers that are known to host copyrighted commercial data — this reduces legal exposure for you and users.

5) Creating the torrent (step-by-step)

1. Compress optional assets: for easier bandwidth and to keep file counts down, zip the assets folder. Keep 'world' files uncompressed if the game expects a specific format.
2. Generate SHA256SUMS.txt for every file and sign it with your PGP key.
3. Open your torrent client (qBittorrent, Deluge, Transmission, or mktorrent on CLI).
4. Create torrent: select top-level folder, set piece size based on total size, enter trackers, add webseed URL if available.
5. Set 'Private' flag only if you're uploading to a private tracker (and then disable DHT/PEX).
6. Save .torrent next to your files and add it to your client to start seeding.

CLI example (mktorrent):

mktorrent -a "udp://tracker.openbittorrent.com:80/announce" -o Whisperfront_Cedar_Expanse_v1.2.torrent -l 20 Whisperfront_Cedar_Expanse_v1.2/
  

6) Seeding and seeding ethics

Initial seeding: When you first create the .torrent, let your client seed uninterrupted until a healthy number of peers have at least one complete copy. Aim for at least a 1:1 upload:download ratio across the swarm for the first 24–72 hours.

Super seeding

Super seeding (available in many clients) helps distribute unique pieces efficiently when you’re the only initial seeder. Use it for large or low-popularity maps.

Seedbox strategy

If you want long-term availability, rent a seedbox (cheap VPS with high upload). Seedboxes increase uptime and give faster propagation without tying up your home connection. In 2026, many creators use seedboxes for early distribution and then rely on the community to keep the swarm healthy.

Maintain a reasonable retention policy

Seed for at least two weeks or until a stable number of seeds exists. If the map becomes popular, keep it seeded longer. Always announce your planned retention and offer an HTTP mirror if possible.

7) Safety and security warnings

Do not include executables

Never bundle EXE, .bat, .msi or unknown installers. Users should never run binaries from map releases. If an installation helper is absolutely necessary, provide source and sign it; better: provide manual install steps only.

Scan and sandbox before release

• Run antivirus and anti-malware scans locally on packages.
• Test import in a clean VM or secondary account to confirm no hidden scripts run on import.
• Provide clear screenshots and sample saves so users can verify contents visually before running anything.

Privacy considerations

Torrenting shares your IP with peers and trackers. If you value privacy, recommend users use a reputable no-logs VPN with torrent support and a kill-switch. Note: Tor is not suitable for torrenting. Explain the trade-offs and include a short privacy paragraph in your README.

Legal & ethical warnings

Do not distribute copyrighted art, music or paid assets without explicit permission. In 2025–2026, many studios tightened policies; community releases that redistribute proprietary files risk DMCA takedowns and tracker blacklisting. If your map references or requires paid assets, instruct users to obtain them legally and list file names (not included files) in the README.

8) Post-release support workflow

Be ready to support import issues and verify claims of corrupted files. Include these tools and steps:

• Provide a small troubleshooting FAQ in README (common import errors, where to place files, max supported client build)
• Keep a public change log and tag releases semantically (v1.2, v1.2.1 for hotfixes)
• Offer re-seed windows: seed heavily for 48 hours after each new release
• Supply fresh SHA256SUMS when you upload a hotfix and re-sign

9) Example case study: packaging a Hytale darkwood world (real workflow)

Scenario: You built a 1.8 GB Whisperfront darkwood map and want to share it in January 2026 after Embark and community attention to procedurally themed maps. Summary workflow:

1. Export world files to Whisperfront_Cedar_Expanse_v1.0/world/
2. Compress optional assets to assets.zip (200 MB)
3. Generate SHA256SUMS.txt for world files and assets.zip
4. Sign SHA256SUMS.txt with your PGP key
5. Create torrent with 1 MB piece size, add 4 reputable trackers and a webseed hosted on a low-cost HTTP host
6. Create a magnet link and post both .torrent and magnet on your distribution page
7. Seed from your seedbox 24/7 for two weeks and enable super-seeding at first
8. Announce release on mod community sites and include clear install steps pointing to the Whisperfront import path

10) Advanced tips and future-proofing (2026 and beyond)

• Provide both .torrent and magnet — magnet links are preferred by many clients in 2026, but .torrent files speed up first-byte peers and preserve tracker lists.
• Automate builds with CI: set up Git-based packaging that generates checksums and signed artifacts for each tag. This reduces human error and increases trust.
• Offer an opt-in listing on community indexers: metadata.json + thumbnail.png allow sites to auto-index your release in an official-looking way.
• If your community grows, consider a small private tracker or gated seed pool to ensure long-term availability while controlling who joins the swarm.
• Watch for studio map tools and official mod hosting (Hytale and Arc Raiders both moved closer to official mod tooling in 2025–2026). Use official hosting where available to reduce legal exposure.

Common pitfalls and how to avoid them

• Broken imports: include exact import steps and tested file paths.
• Malware scares: never include executables; sign and checksum everything.
• Dead torrents: seed longer, use seedboxes, and consider webseeds.
• Copyright issues: do not redistribute assets you don't own; document dependencies instead.
• Tracker takedowns: keep mirrors and webseeds and provide fresh magnet links if trackers disappear.

Actionable checklist before you publish

1. Confirm legal rights to redistribute everything in the pack
2. Organize a predictable folder structure and README
3. Generate SHA256SUMS and sign them with PGP
4. Create torrent with a sensible piece size and trackers; add webseed if possible
5. Seed with super-seeding and/or a seedbox; keep availability for at least two weeks
6. Publish both .torrent and magnet, include install steps, screenshot and changelog

Closing notes — a pragmatic future for map sharing

As of 2026, the map-sharing ecosystem is maturing: studios like Embark and Hypixel are providing better support for community content, and indexers expect structured metadata, signed releases and clear licensing. Follow the steps above to make your Hytale darkwood worlds or Arc Raiders maps reliable, trustworthy and easy to use — and you’ll get fewer support requests, fewer security scares, and a healthier community swarm.

Final warning: This guide does not replace legal advice. If a map includes third-party assets or large amounts of licensed content, get written permission before you distribute it.
