TaCZ Refabricated — Unofficial Fabric Port

Unofficial community port. Not an official TACZ release, and not affiliated with, reviewed by, or endorsed by the TACZ Dev Team.

What this project is

Timeless and Classics Guns: Zero (TaCZ) is a modern firearms mod featuring highly customizable guns — attachments, optics, ammo types, and a gun-smithing workbench for crafting and modifying weapons.

This project is a community port of that mod to the Fabric loader on newer Minecraft versions. It adds no new guns or gameplay of its own; the goal is to make the existing mod run on a platform and game version it did not previously support.

Credits — original work

The original mod is licensed under GPL-3.0, which permits this port. This project is likewise released under GPL-3.0.

What changed from the original

This is a port, not a content fork — but the target game version removed or reworked a number of APIs, so substantial internal rework was required:

• Rendering layer partially rewritten. The stencil buffer, which upstream relied on for through-the-optic (in-scope) rendering, no longer exists on the target version. The scope rendering path was reimplemented. Some visual effects therefore differ from the original, which is a known trade-off.
• Networking updated to the current packet/codec system.
• Data-pack and model loading updated for the new resource format (directory naming, item model definitions, component-based item data).
• Gun pack loading fixes so that existing third-party gun packs — including ones written for older versions — continue to work.

Status: test build

Playable, but under active testing. Expect bugs.

Requirements

Exact Minecraft and dependency versions are listed on each file — check the file you are downloading.

Fabric only. There is no Forge or NeoForge build of this port.

Installing gun packs

Gun packs go in .minecraft/tacz/ — not tacz_backup. .minecraft/ ├── tacz/ ← put gun packs HERE (created on first launch) │ ├── some_pack.zip ← .zip works directly, no need to extract │ └── another_pack/ ← extracted folders also work └── tacz_backup/ ← input directory for the legacy pack converter only

A folder or zip is recognised as a gun pack only if gunpack.meta.json exists at its root:

```json { "namespace": "your_pack_namespace" } Without that file the pack is silently skipped.

If a pack doesn't load, check in this order Is it in tacz/ rather than tacz_backup/? Does gunpack.meta.json exist? Is the zip nesting correct? That file must sit at the zip root, not inside zip/packname/. Check the log for Mod version mismatch. Note on the reported mod version This port reports its version with the upstream baseline first (1.1.8), followed by build metadata after a +. Under the SemVer specification build metadata is ignored when comparing versions, so gun packs that declare a requirement such as "tacz": ">=1.1.8" load normally.

Known limitation: packs requiring TacZ:Arcana Some gun packs cannot be loaded by any TACZ build that lacks TacZ:Arcana. Symptom: missing textures (purple/black) and models not rendering, while gun entries, names and recipes all appear correctly.

To identify such a pack, extract it and look for:

recursion/taczpack.dat (often tens of MB — most of the pack's size), or data/<namespace>/expansions/taczexpands.data, and no .png / .ogg / geo_models/ / textures/ anywhere in the pack Those packs ship their models, textures, animations and sounds encrypted inside that .dat, leaving only JSON indexes on disk. Decryption is performed by the separate mod TacZ:Arcana, which is Forge-only and closed-source.

No TACZ build contains that decryption logic — not the original Forge mod, not the upstream Fabric port, and not this one. This is therefore not a defect in this port and cannot be resolved here.

Licensing Two independent licenses apply:

Scope License Code GPL-3.0 (inherited from the original mod) Bundled default gun pack assets CC BY-NC-ND 4.0 The code is copyleft — redistribute modifications under GPL-3.0. The bundled default pack assets are NonCommercial + NoDerivatives: they may not be sold, and may not be modified and redistributed. To build your own pack, create a separate pack rather than editing the default one.

Reporting issues Please report issues to this project, not to the original authors — they have no obligation to support this port. If an issue is confirmed to originate upstream, it can be raised there afterwards.
