About this project
What does Yttr add?
Fabric API, QSL, or Sinytra Connector + Forgified Fabric API is required. EMI is strongly recommended.
Yttr is an expansive mod for Fabric & Quilt, sort of existing as a love letter to 1.4-1.6 modded. It contains fresh takes on a lot of common features, interesting worldgen, custom music, and all-new mechanics.
Starting as a loose collection of useful tidbits, Yttr has grown into a more cohesive mixture between a content mod and a vanilla overhaul. Presented as three "content branches", extending those provided by vanilla; Void for the Overworld, Scorched for the Nether, and Continuity for the End.
The first "progression gate" in Yttr is using the multi-mode Yttric Rifle to blast an obsidian/diamond spike into the bedrock, smashing it open, revealing a geyser of liquid Void — created years (or versions) ago due to an alchemical disaster, also resulting in the creation of the familiar Wasteland biome. After thorough preparation, you might even be able to dive through the Void to fast-travel to places you (or your friends (or rivals)) have smashed open geysers elsewhere. If you're not sufficiently prepared, well, even your items are not protected from the Void's universal dissolution...
Scorched acts as a complete revamp of the top of the Nether, turning it into an ominous soot-covered biome, and making it simple to access (because let's be honest, getting on top of the Nether is not difficult). Your farms won't break, as nothing can spawn in the Scorched Summit on its natural blocks.
Roots of Continuity can be found underneath floating End islands, and smashing them with a pickaxe yields a Drop of Continuity and drops the island into the abyss — however, you may want to watch your back...
Also offered are "abominations", providing a solution to autocrafting and item sorting that isn't just a block with a funny texture. (Okay, it's a block with a funny model.) Put a Skeleton on a table, surgically combine Silverfish and Creepers and house them in a Bee Nest, or splice together an Enderman and Zombie and magically bind them to a hopper — because of course you will just to make your logistics easier, <s>you monster</s>.
Yttr treats crafting more as a mechanic than an interface, tightly integrating with the world around it. From automatically crushing and bottling gaseous Shroomlight, to stuffing a skeleton in a snare and feverishly strapping it to a table, Yttr tries to avoid recipes that can be solved by a digital storage system. Every recipe type also comes with detailed EMI integration.
Also included are a plethora of useful "Vanilla+" pieces — the Dopper, a dual-output round-robin hopper; the Flopper, a sideways hopper; the Chute, allowing you to send items downward or center items shot from a Dropper; the Yttrium Button, a one-tick button; half-tick delayed note blocks, and even a few more things still.
There's even more to the mod than mentioned here — solvent-weldable plastic Bloques®, fancy lamps, permanent Neodymium magnets, a centrifuge, Delicaceness of Deep-Sea Squeeze Trees, multiple new enchantments and curses, a new form of circuitry derived from InfraRedstone (not yet finished), ...
Check out the wiki for a thorough explanation of <s>everything</s> some things — it has not yet been updated for the latest version, and is stuck on v0.4.3. We're working on getting it updated. You can come chat on Discord or Matrix about it, too.
