About this Modpack

Title Image

Welcome to Polymania!

Polymania is a kitchen-sinky, Fabric Server-Side modpack, which main goal is to provide the classic modded experience, while being easy to install and use.
It's ideal for a server you want to play on with your friends, as the only thing needed is a place to host it and vanilla Minecraft client!

This modpack is contains:

Installation.

Modpack is available on Modrinth, but can be easily installed on any hosting service that supports custom jars.
Naturally it can also be installed on Modrinth Servers using it's builtin modpack installer.

Provided installer (Recommended).

Every release of a modpack provides extra file named server.jar. Just download it and run it like any other Minecraft server (see MC wiki for running it locally, or follow your server hosting tutorial about using custom jars). Only thing you will need to do is to accept Minecraft's eula.

Using mrpack4server.

You can use mrpack4server just as it's described in it's readme.
Officially provided server.jar uses pre-configured version of it set to download the pack, so there should be no functionality difference aside of having to set it up manually.

Other methods.

Other known methods of installing modrinth modpacks include mrpack-installer, itzg/minecraft-server docker image or any other compatible installer, through I wouldn't suggest using them for non-technical users.

Faq

Can I check all recipes somehow? Also can I hide the block names on top of the screen!

Yes! You can use /polydex command to show all available item recipes. Block/Entity names on top of the screen are also
handled by the Polydex. You can read more about it here!

Can I run this modpack on the client/singleplayer?

It might work, but it's not as tested as running this pack on a server. At least for versions 0.3.0-beta.3 and newer it should work.
Older versions will be missing mods, if not crash outright. Try for yourself.

Can I use Geyser with this?

Currently? Sadly not. Due to many differences between how java and bedrock handle many technical / datapack / resourcepack features, this modpack won't work correctly with Geyser users. So even if they managed to join, they likely won't see textures and models correctly, while also not being able to use some items and blocks at all.

Does ViaVersion / ViaBackwards work with this?

Heavily depends on versions you use. Generally it might work in some cases, where enough things didn't change, but at least with older versions things will work worse if not at all in case it's missing required behaviour/feature. In case of newer version, it's possible some things won't work due to format / display changes in Minecraft resource pack features, through it should be way more compatible.

Modified mods, included assets and licenses.

Polymania uses forks of mods, which source code/changes you can see check at PolymaniaForks github page. Their usage might change as the pack updates.

Additionally it includes:

  • It includes port of Dark Paintings as a datapack/resourcepack combo, which you can find under config/openloader/data/DarkPaintings.zip.
  • Modified version of Moss Carpet Overhang resource pack form Vanilla Tweaks, making it cull more when placed on sides of other carpets/blocks. You can find it in polymer/override_assets/assets/minecraft/(block|item)/moss_carpet.json and polymer/override_assets/assets/minecraft/textures/block/moss_carpet_overlay.png
  • Unsanded by unascribed, modified to exist as it's own font instead of overriding vanilla. You can find it in polymer/extra/Unsanded-1.1.1-custom.zip.
  • Lato Regular Font as an extra usable font. You can find it in polymer/override_assets/assets/polymania/font/lato.
  • Tweemoji as emoji's used with Styled Chat. You can find it in polymer/override_assets/assets/polymania/textures/emoji.
  • (0.4.4 and older) Fork/Development version of PolyMc by TheEpicBlock and PolyConfig by TheEpicBlock, a translation layer without which this modpack would never exist, which source you can find on GitHub: PolyMc, PolyConfig. You can find them in mods/PolyMc-(ver).jar and mods/polyconfig-(ver).jar.

Frequently Asked Questions

Polymania! server crashes or won't start – what to do?

Most common causes: insufficient RAM or wrong fabric loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 8 GB. For "Mixin" or "ClassNotFoundException" errors: modpack version and loader don't match. With Mado Hosting, loader and Minecraft version are auto-configured on modpack install – preventing most startup issues.

How much RAM does a Polymania! server really need?

Minimum 6 GB, recommended 8 GB for stable performance. per 5 players. Important: Minecraft modpacks need more RAM than vanilla – plan extra per additional player. With Mado Hosting, you can scale RAM up live at any time without data loss (from €7.800000000000001/month).

Can I add custom mods to Polymania! without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (26.2). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.

Polymania! server lagging – performance tips

1) Increase RAM to 8 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time. With Mado Hosting, all servers run on NVMe SSDs with dedicated CPU cores – eliminating hardware as a bottleneck.
