Only Server Gunpack
by hxwi1
Only Server Gunpack lets a server host TaCZ gunpacks in memory so that players receive them over the network without ever holding the raw files.
What it does
The server scans its own TaCZ gunpack folder and sends the packs to joining clients over the network. On the client, the packs are assembled in RAM and offered to TaCZ through the same RepositorySource interface that Forge uses for local files, so TaCZ loads them as if they were stored on disk. Nothing is written to the client's disk, and the packs are cleared from memory when the player disconnects.
Because players never receive the raw files, they cannot copy or spread the models, textures and sounds to other places. Each pack is checked with a CRC32 integrity value to confirm byte-level fidelity. Server owners can replace the files in the server gunpack folder and run the osg reload command to apply changes. Players already connected keep the old version, and anyone who joins afterward receives the update. Packs loaded through the API cannot be hot-updated this way. The mod is published for Forge only, for Minecraft 1.20.1, under All rights reserved. It is not open source.
Key features
Server-side gunpack distribution
The server holds the gunpacks and sends them to players, so clients join without installing or configuring any packs.
In-memory loading
Received packs are kept only in RAM and discarded on disconnect, so the client never writes them to disk.
Reload command
After replacing server gunpack files, an osg reload command applies the new versions to newly joining players.
Integrity check
A CRC32 value confirms that each delivered pack matches the server copy at the byte level.

What the author says
Server-side TACZ gunpack distribution. Zero setup for players — join and play. Pure in-memory, nothing touches disk. TACZ loads gunpacks through Forge's RepositorySource interface — it scans the tacz/ folder, wraps each pack as a PathPackResources, and hands them to Minecraft's resource system.
