Packer

by AverageTurtle

Packer lets server owners host custom item models and textures on a Fabric server, with players receiving the assets without installing a resource pack.

FabricServer-side onlyApache License 2.0Open source1.21.10 – 1.21.11

What it does

Packer runs only on the server, so players join without installing anything. Custom item models are defined on the server and sent out through a server-side model system, which lets a survival server offer custom-looking items while the vanilla client handles them normally. An item model is built from three parts: an item model definition, the item model itself and its textures.

Assets are uploaded to a folder that Packer places under a UUID, and references to the files are replaced with that UUID when uploading, so the names in the source json stay readable while working locally. Files are published for Fabric only, for 1.21.10 and 1.21.11, with 0.1.0-Alpha for 1.21.11 as the latest build, released under the Apache License 2.0. The code is open source and public links exist for the source, the issue tracker and the wiki.

Sessions for the web portal last only until the player leaves the game or the server restarts, so a new code is needed afterwards. A player who wants a quick link needs the packer.link permission, and the portal requires an authenticated login before it issues a generated code.

Key features

  1. Server-side custom models

    Custom item models are delivered from the server, so players need no resource pack to see them.

  2. Item model definitions

    Each custom item is described by an item model definition that points to its model and textures.

  3. Shared assets

    Textures and resources can be reused between assets, and assets from other resource packs can be referenced.

  4. UUID-based uploads

    Uploaded files are stored under a UUID folder and referenced by it, so local file names are replaced automatically.

Use cases

Survival servers

Server owners add custom items to a survival world without asking players to install a resource pack.

Model uploads from a web portal

Server owners open the web portal with a generated code, which requires an extra port open on the server.

Who it’s for: Server owners who want custom item models on a Fabric server, and the staff who manage uploads and the portal access codes.

Questions

Does a player need Packer installed to see custom models?

No. Packer is server-side only, so the models reach players without any client installation.

What port does the web portal need?

The web portal needs at least one extra port open on the server, and the portal is then reached from a web browser through the server's public IP.

Which game versions does Packer support?

Packer has Fabric files for 1.21.10 and 1.21.11, and 0.1.0-Alpha for 1.21.11 is the latest build.
