Survival friendly, dynamic, server-side custom models for Minecraft!
What is Packer?
Packer allows you to upload, manage, and utilize custom models in survival Minecraft servers. Using a mix of a user-friendly(ish) web portal and ingame commands. Complete with dynamic reloading of uploaded pack data. Plus commands to apply models to items in a survival friendly way!
Getting started
To get started add the mod to your fabric server. Run once to generate config file and follow directions below!
Configuration
In order to utilize packer you will need at least one extra port in order to access the web portal server. Justs put your servers PUBLIC ip and port and you are ready to go!
#Packer Configuration
# Set server-address to your Public IP or Domain.
server-address=YOUR_IP
# Your open port!
port=YOUR_OPEN_PORT
# The maximum upload size of files in bytes
max_upload_bytes=15000000
Accessing your web portal
You can accessing your web portal in any web browser using your servers public ip! If you want a quick link you can type /packer link (requires packer.link permisions) in game to gain a quick link. To gain access to your portal you must authentic. In order to authentic you can run /packer auth in game. Put the generate code in your web portal. Due note that all sessions last ONLY until you leave the game or the server restarts.
Uploading your first model
To upload a model in packer you need 3 things.
- The item model definition
- The item model
- The texture(s)
you may reuse these resourcess between assets as normal for resource packs
You may author these assets as you would for any other resource pack. Packer will place all assets you upload in a folder under YOUR UUID. As a shorthand for working with files locally you can use packer_id inside any json file. This will be replaced with your UUID upon uploading.
More info can be found on the (wip) Wiki.

Server lagging with Packer – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Packer consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
