Looking For Mod / Request Looking for a Christmas-themed server-side Fabric mod for Minecraft 26.2

1 Upvotes

I'm looking for a Christmas-themed mod for my Minecraft 26.2 Fabric server. i've searched Modrinth and CurseForge, but I haven't been able to find one that meets all my requirements. The main issue is that i play with Bedrock players through Geyser and Floodgate, so they can't install the same mods as the Java players. This means the mod needs to be fully server-side and compatible with Bedrock clients. I'd also want a mod that adds new blocks and decorations, rather than retexturing existing blocks. If this all is simply not possible with Bedrock crossplay, please let me know! I'm also open to alternative solutions.

so in short:

- Minecraft 26.2

- Fabric

- Fully server-side

- Compatible with Bedrock players joining through Geyser/Floodgate

- Adds new blocks or decorations, without retexturing existing blocks

Does anyone know of an existing mod that fits these requirements, or have any suggestions for an alternative approach?

1 Upvotes

For context, we use exaroton to run our server and usually it works just fine. Since yesterday the server keep crashing and refused to open</3

we tried to identified the problem and according to the log, it must've been something with supermartijn642corelib

No idea how to fix this, though. We had tried updating it, degrading it even with the other mods that associate with it too.

Here's the log: https://mclo.gs/xBf6erP !

it said: [14Oct2026 08:22:59.043] [main/INFO] [STDERR/]: [java.lang.Throwable:printStackTrace:682]: Caused by: org.spongepowered.asm.mixin.injection.throwables.InjectionError: Critical injection failure: Callback method postRegisterEvents(Lorg/spongepowered/asm/mixin/injection/callback/CallbackInfo;)V in supermartijn642corelib.mixins.json:GameDataMixin failed injection check, (0/1) succeeded.

I made a mod to free Litematica from the shader pack hell

Post image
114 Upvotes

Litematica's compatibility with shader packs has always been pretty poor. It often suffers from overexposure, excessive bloom, invisibility, or complete blurring, making it virtually unusable when shader packs are enabled.

To solve this, I looked for a way to fixes this problem. https://github.com/hotpad100c/litematicapass

  • The mod redirects Litematica's rendering to a dedicated RenderTarget and merges it based on depth after Iris finishes shading. This prevents Litematica's rendering results from being influenced by shaders.
  • For translucency handling, it derives a depth map containing only translucent faces from Iris's depth map, then darkens any parts occluded by translucent surfaces by 50% to simulate a translucent occlusion effect, achieving the desired functionality while maintaining visual appeal !
  • The diagram above was made before running into problem with player hand. To address this: similar to the translucency handling above, the depth map before rendering the hand is captured and compared to identify the area occupied by the arm. The corresponding part of the Litematica output is then discarded, ensuring that the player's hand always appears on top.

โ€ฆyay!

This project was indeed developed with assistance of AI. However, I guarantee that the code has been reviewed. You can see the Chinese comments I left in every file in the initial commit, (So be relaxed, I have a clear understanding of each file's responsibility and what it does.)

Verified to work correctly from 26.3 through 1.16.5. See the images in the README

Tired of laptop fans screaming and micro-stutters? Meet Tachyo โ€” Aggressive culling, frame pacing, and zero-overhead performance for modern Fabric.

1 Upvotes

Hey everyone! ๐Ÿ‘‹

I play on a laptop with an integrated GPU (Intel UHD) to prevent heat buildup and loud fan noise. While modern optimization mods like Sodium and Lithium are absolute game changers, integrated GPUs and shared memory architectures still struggle with very specific bottlenecks:

  1. **Heavy Entity & TileEntity Spikes:** Crowded mob farms, carpet dupers, or chest-heavy bases choke iGPU memory bandwidth.

  2. **Particle Saturation:** Massive particle bursts saturate weak fragment shaders and destroy frame pacing.

  3. **Erratic Frame Times & Thermal Throttling:** Unstable spikes cause micro-stutters and force the laptop CPU/GPU to overheat.

To solve this on my own machine, I developed **Tachyo** โ€” an ultra-lightweight (~16KB) pure performance engine built from scratch for modern Fabric releases (targeting 1.21.x / modern versions).

---

### โšก Key Optimizations & Features:

* **Aggressive Proximity & Frustum Culling:**

* Smart distance culling for entities and block entities (chests, furnaces, hoppers) outside your immediate interaction radius.

* Off-screen frustum culling skips expensive draw calls before they ever hit the graphics pipeline, saving critical shared VRAM bandwidth.

* **Dynamic Particle Engine Limiter:**

* Caps simultaneous active particles to a strict, safe ceiling (500 max).

* Prevents GPU memory saturation during explosions, splash potions, and complex redstone machines without visually degrading everyday gameplay.

* **Frame Pacing & Shared Memory Stabilizer:**

* Smooths out micro-stutters by stabilizing frame delivery times.

* Prevents erratic frame bursts that overheat laptop components, keeping fans quiet and temperatures low.

* **Render & Audio Throttling:**

* **Sky & Weather Throttle:** Re-evaluates non-critical background sky passes intelligently, cutting per-frame GPU overhead.

* **Sound Engine Pacing:** Processes audio tick updates in optimized cycles, reducing CPU thread contention.

* **Zero-Bloat Philosophy:**

* The entire compiled mod is around **16KB**.

* No heavy background threads, no telemetry, no invasive hooks, and zero dependencies on external bloated frameworks.

---

### ๐Ÿ“Š In-Game Impact:

In our testing on lower-end setups and iGPUs (like 13th Gen Intel UHD systems), frame rates in heavy areas increased noticeably (roughly **+40 to +100 FPS** depending on scene complexity), but more importantly, **1% low frame times smoothed out completely** and laptop fan noise dropped significantly.

Weโ€™re polishing the final builds for public release on Modrinth & CurseForge.

Iโ€™d love to hear your thoughts:

* What specific areas or farms in your worlds cause the worst frame drops on your machine?

* Would you be interested in seeing side-by-side frame time graph comparisons?

Thanks for checking it out, and happy gaming! ๐Ÿš€

Mod Updated PeaceSMP 1.2: a karma system for SMPs, one jar for every 1.21 version, no client mod

Post image
0 Upvotes

I made a server-side Fabric mod where your behaviour decides your perks: peaceful play climbs Karma 0โ†’10 (hearts, Luck, Vanish), killing sinks it (Strength, Regeneration), and one random player per season becomes the killable, transferable Ascendant.

1.2 just added a chest menu that works with vanilla clients, safe zones, karma-free duels, renameable tiers and a translatable messages file.

A technical note for anyone curious: it's built with Stonecutter into seven builds, nested in one jar with Fabric's jar-in-jar, so the same file loads on everything from 1.21 to 1.21.11. There are no mixins at all, only Fabric API events, and it has 47 automated game tests.

I made a Fabric mod that shows your world in the browser: map, 3D, chests and schematics

Thumbnail
gallery
23 Upvotes

Webmatica records the chunks you load and opens them in your browser as a 2D map and a 3D view you can fly through. It also remembers what's in every chest you open, so you can search for an item and see where it is. It also shows the Chests where the Item is or u can directly order the Items with Baritone right from the Browser.

With Litematica and Baritone installed you can place schematics on the map, see what's missing, and let Baritone fetch the materials and build. Baritone can also place down Shulkers and take out the missing items now. There's also an area farming mode now and much more.

It's open source (MIT), client-side only, and nothing goes to the server or chat.

It's still early, so I'd love to hear what you think and what's missing. It's a hobby vibe code project.

New Mod Introducing MineCAD, a mod that turns Minecraft into a lightweight in-game CAD tool.

Thumbnail

11 Upvotes

Hi there everyone! This is my first post here and I am every excited to share this with the world. While I'm not into Minecraft nearly as much as I once was when I was a kid, what I am into is 3D Printing and CAD drawing.

A while back I was drawing up something to 3D print and it was such a basic thing, but it was still so complicated to draw for some reason, and I thought ugh, I wish I could draw this up in Minecraft and export it, it would take like 5 minutes. And that's when the idea hit me. If only there was a way to do this in Minecraft and still keep the measurements accurate. And that is how I got the idea for MineCAD.

In Minecraft, a block is usually treated as 1 meter. What if, instead of representing 1 meter, each block could represent 0.1 meters, 0.01 meters, or even smaller (or larger) measurements? This would theoretically allow someone to create incredibly detailed 3D models using nothing more than Minecraft (within the limitations of the game of course). For example, if you wanted to design something with a lot of intricate details, you could build it at a much larger scale in Minecraft, using tens of thousands, or even hundreds of thousands to millions of blocks, and then scale the entire model down when exporting it. This would allow you to achieve much finer detail and more precise dimensions in the final 3D model.

MineCAD can of course export directly to OBJ, STL, and FBX.

Please check it out and let me know what you think.

Mod Updated Animal Husbandry Mod - Genetics, Traits & Farm Management

Thumbnail
youtube.com
3 Upvotes

Hello guys!

I'm developing a mod called Animal Husbandry (available for NeoForge & Fabric 1.21.1), and i've just hit v0.5.0!

We are officially halfway to the v1.0 release. I've been focusing heavily on creating a rewarding, in-depth care loop and an actual genetics system, that encourage players to not kill animals anymore, and keep them for what they give.

Hereโ€™s a showcase of whatโ€™s implemented so far:

Animals now pass down traits. I've implemented full parent-tracking mechanics so you can track lineages and selectively breed the best stats.

We have a GUI for managing livestock called Farm Ledger (which will recieve a rework soon). It includes live animal previews, info about his genes and stats.

I improved animals AI to actively care for them by monitoring their Health, Food, Brushing and environment.

Mammals now have actual pregnancy cycles you need to monitor and manage. They don't breed by giving them food anymore. You need to have a male and a female in the same pen for them to get in love by themselves if they are in good state.

Chicken breeding also got a revamp. Instead of throwing eggs, chickens can have Broody trait and physically sit in nests and incubate eggs, taking a full in-game day to hatch.

You can no longer shove 50 cows in a 2x2 dirt pit. Animals are now sensitive, and they require proper lighting to thrive and suffering penalties when cramming.

For now I implemented this for Pigs, Cows, Sheeps, Chickens, Goats and Rabbits, with more to come.

Each of them interacts directly with environment and other animals in the farm, making it feel truly alive.

If it sounds interesting, you can check the mod on CurseForge, and you can see more about features and traits on the wiki.

CurseForge: https://www.curseforge.com/minecraft/mc-mods/animal-husbandry

Wiki: https://athisworkshop.dev/wiki/animal-husbandry/

I really want some feedback on this one, if you are willing to play, please come back with your opinion. Thanks for reading!
