Resource packs
A resource pack changes how the game looks and sounds for the people who join your server — textures, models, sounds, fonts. It runs entirely on the player's client, works on any engine, and is available to everyone.
- What a resource pack changes (and what it doesn't)
- How players receive it on join
- How to upload one and optionally require it
What a resource pack is
A resource pack is a .zip of client assets. When a player joins, the server hands them a
download URL plus a checksum; their game downloads the pack and applies it locally. Nothing
about the server's behavior changes — only what the player sees and hears.
| Resource packs change | Resource packs do not |
|---|---|
| Textures, models, sounds, fonts | Change server logic, drops, or recipes |
| The look of blocks, items, the UI | Run code on the server |
| The experience on each player's client | Persist gameplay data (that's the world and datapacks) |
Which engines support resource packs
All of them. Delivery is part of vanilla Minecraft, so a resource pack works the same on a Paper, Fabric, or Forge world.
Upload a resource pack
- Open the world in Worlds.
- Upload your resource pack
.zip. Lanzinha computes its checksum and serves the download URL to players automatically. - Optionally turn on require resource pack so players must accept the pack to play.
The per-file limit is 512 MiB, and uploads count against your account storage quota (an upload is rejected if it would push you over). Re-uploading a file with the same name replaces it, and you can remove the pack anytime no room is running on the world.
Leave "require" off if you just want to offer a look players can decline. Turn it on when the pack is essential — for example a UI or texture overhaul your world is built around.
A resource pack is client-side: it doesn't change the world or the server, only how the game looks for players who download it. To change behavior, use a datapack. Lanzinha is not affiliated with Mojang or Microsoft.
