Dimensional Doors Mod Guide: Pocket Dimensions, Dungeons, Limbo & Rifts
Dimensional Doors tears holes in reality, giving players access to pocket dimensions, procedural dungeon crawls, and the haunting Limbo dimension filled with watching Monoliths. Craft dimensional doors to create private hideaways, explore treasure-filled dungeon chains, and master the art of rift management. Every broken door leaves a scar on the world, and something in the dark is always watching.
Overview
Dimensional Doors adds five types of magical doors that punch through the fabric of reality, connecting the Overworld to a network of pocket dimensions. Some pockets are empty voids ready for private building. Others are dungeon chains packed with traps, puzzles, and treasures. And one of them, Limbo, is a dark, fog-shrouded realm filled with enormous entities that want nothing more than to stare at you until you disappear.
The mod also introduces Rifts: fractal tears in reality that form whenever a dimensional door is broken without being properly closed. Rifts grow over time and must be managed using crafted tools that also yield the mod's most important resource, World Thread. The full crafting progression runs from a basic door to a Tesselating Loom, then through increasingly exotic materials gathered from Limbo itself.

Getting Started
- 1
Craft Your First Door
The easiest entry point is the Wood Dimensional Door, crafted by placing two Oak Doors on either side of an Ender Pearl in a crafting grid. This door is mostly used for backtracking through dungeons, but it gets you familiar with how dimensional doors behave. Place it in the world and right-click the glowing portal side to step through.

Find or Create a Dungeon Entry
Look for Gateway structures in the Overworld — rare archways made of Unravelled Fabric that contain Iron Dimensional Doors leading into dungeon chains. Alternatively, craft a Gold Dimensional Door (two Gold Doors around an Ender Pearl) to create your own dungeon entry on demand. Gateways are the organic discovery path; Gold Doors are the deliberate one.
- 3
Learn the Door Rules Inside Dungeons
Inside dungeon pockets, Iron Dimensional Doors always lead deeper into the dungeon chain. Wood Dimensional Doors lead back toward the entrance or return to the Overworld exit. Every chest found in a dungeon can contain World Thread, which is the primary crafting material you are farming. Bring a full stack of Cobblestone or Dirt before entering — you will need to bridge gaps and block traps.
- 4
Collect World Thread and Craft a Tesselating Loom
World Thread drops from dungeon chests and can also be obtained by using a Rift Remover on any Rift in the world. Once you have at least four World Thread, craft Stable Fabric at the Tesselating Loom. Stable Fabric is the backbone for Dimensional Doors, the Rift Blade, and most advanced tools. Building the Tesselating Loom requires Scaffolding, Black Fabric, World Thread, and a vanilla Loom.

Set Up Your Private Pocket
Craft a Quartz Dimensional Door (two Quartz Doors around an Ender Pearl) to access your personal pocket dimension — a large white room made entirely of white Fabric of Reality. This space is yours alone, unaffected by Overworld events, and perfect for secure storage or private building. Every player gets their own separate pocket even if multiple players use the same door.
Dimensional Doors
Each door type has a distinct purpose. Placing any dimensional door directly on the block beneath an existing Rift activates that rift, turning it into a portal leading to wherever the door normally goes. Placing a door anywhere else creates a new portal from scratch. Always enter through the glowing portal face — walking through the back of a door does nothing.
Wood Dimensional Door
The cheapest door to craft. In dungeons, it usually leads back to the previous room or to the Overworld exit point. Useful for retreating when a dungeon room goes wrong. Placing one in the Overworld creates a public pocket entry, but this type of door offers no treasures or personal space — it is primarily a backtracking tool inside dungeon chains.
Iron Dimensional Door
The workhorse door of the mod. When placed in the Overworld, it creates or enters a public pocket dimension — an empty black void useful for communal building projects or neutral storage. Inside dungeons, every Iron Door leads deeper into the chain. The public pocket is shared between all Iron Doors placed in the same world, unlike the private pocket.
Quartz Dimensional Door
Leads to the player's personal pocket — a large, fully lit white room made of white Fabric of Reality. The pocket belongs to the individual player: two different players each see their own private room when using the same Quartz Dimensional Door. This is the go-to pocket for secure storage vaults, private bases, or a safe AFK spot away from hostile mobs.
Gold Dimensional Door
The most expensive and most rewarding door. Leads directly to a dungeon pocket chain filled with loot, puzzles, and traps. This is the crafted alternative to finding a Gateway structure in the Overworld and is the recommended path for players who want to farm World Thread reliably.
Unstable Dimensional Door
Crafted with an Eye of Ender instead of an Ender Pearl. Leads to a completely random destination — another rift, another door, or straight to Limbo. Using it repeatedly is dangerous. Treat this door as a last resort or curiosity, not a reliable transport tool.
Dimensional Door Recipes
Every dimensional door has a portal side and a back side. Only the glowing, active portal face teleports you. Walking through the back does nothing. When placing a door on a Rift, place it on the block directly beneath the rift, which activates the rift rather than creating a new portal next to it.
Pocket Dimensions
Dimensional Doors adds four separate dimensions, each accessed through a different door type. The Personal Pocket and Public Pocket are player-created spaces. Dungeon Pockets are procedurally generated adventure zones. Limbo is where players end up when things go wrong.
Personal Pocket Dimension
Accessed via the Quartz Dimensional Door. The entire room is lined with white Fabric of Reality, which can be replaced by right-clicking with any block — making it easy to redecorate. The pocket persists between sessions and is unaffected by anything that happens in the Overworld. It is effectively a dimensionally isolated chunk of space. Set a Respawn Anchor here rather than a Bed, since Beds explode in non-Overworld dimensions.
Public Pocket Dimension
Accessed via the Iron Dimensional Door placed outside of a dungeon context. This is a shared empty black void — multiple players can build here, and all Iron Doors in the same world connect to the same public space. Less commonly used than the personal pocket, but useful for server community projects.
Dungeon Pocket Dimension
The main adventure content of the mod. Dungeon pockets are chains of interconnected rooms with six room types: Hub rooms with four or more iron doors, SimpleHall connectors, ComplexHall rooms with piston puzzles, Trap rooms with a survivable hazard and a reward chest, Exit rooms that link back to the Overworld via a Wood Door, and DeadEnd rooms with no other exits — these usually hold the best treasure. Every Iron Door takes the player deeper; every Wood Door offers a way back.
Limbo
Limbo is a dark, fog-shrouded dimension made almost entirely of Unravelled Fabric. Players end up in Limbo by dying in any pocket dimension, falling into the void inside a pocket, or being spotted by a Monolith. The dimension is intentionally disorienting, with pitch-black darkness broken only by the glowing red eyes of Monoliths hovering at various heights and the ambient sound of something tearing.
To escape Limbo, travel downward to the lowest depths of Limbo, around Y level 0 to 20, and find Eternal Fluid. This is a glowing liquid that pools at the bottom of the dimension. Walk into it and it will teleport the player back to the Overworld, depositing them near the point where they entered Limbo.
Limbo is also a source of two important materials. Infrangible Fiber can be mined from deeper Limbo terrain using a Silk Touch pickaxe. Frayed Filament is obtained by detonating Unravelled Fabric blocks — a controlled explosion yields a stack of them. Both feed into the late-game crafting progression at the Tesselating Loom.
Monolith
Limbo, Dungeon Pocket wallsMonoliths are large floating entities that appear as tall dark pillars with pairs of glowing red eyes. They are completely invulnerable — attacks deal no damage and only increase their aggro toward the attacker. Each Monolith has a random aggro cap between 25 and 100 points. When a player is in their line of sight, aggro increases. When the player looks away or moves beyond 35 blocks, it decreases. Once aggro reaches 250, the Monolith teleports the player directly to Limbo. In dungeon pockets they lurk just outside the walls — breaking walls carelessly can put a player directly in a Monolith's sight line.
Dungeon rooms contain pressure plates, tripwires, and disguised traps. Do not click Beds found in dungeons — they explode. Do not ride Minecarts unless you are certain of the destination — they commonly trigger trap sequences. Avoid breaking walls: Monoliths spawn just outside the dungeon structure and will see through any gap created.
Rifts
Rifts are fractal-shaped tears in reality that form whenever a Dimensional Door is broken without being properly closed first. They also appear naturally in rare Rift Clusters across the Overworld — these clusters lead to other distant clusters and can be used for extremely long-range transport. Rifts grow logarithmically over time; a small rift left alone will slowly expand and spread, eventually consuming nearby blocks.
To pass through a rift without placing a door, right-click it with a Rift Blade. To enter a rift, place any dimensional door on the block directly beneath it, which converts the rift into an active portal. New players are often alarmed when rifts appear after breaking doors; the rift is manageable, but ignoring it for long periods will cause it to grow out of control.
Rift Management Tools
Rift Remover
The most important rift tool. Crafted with 4 Gold Ingots and an Ender Pearl, the Rift Remover has 100 durability and loses 1 durability per rift closed. Right-clicking a rift's core closes it and drops World Thread, making rift removal directly profitable rather than just maintenance. Rifts near the core are closed as well, so one use can clean up a small cluster.
Rift Stabilizer
Has 6 durability and stops a rift from growing without closing it. Useful when a rift is inconveniently located but the player cannot afford to spend a Rift Remover use yet, or when a rift has been opened deliberately for later use. The stabilized rift will remain at its current size indefinitely.
Rift Signature
A single-use tool (durability 1) that creates a linked pair of rifts. The first click stores a location; the second click creates two rifts connected to each other. This allows short-range teleportation between two fixed points but cannot cross dimensional boundaries.
Stabilized Rift Signature
Has 20 durability and works differently from the basic Rift Signature. The first click permanently binds to a location; every subsequent click (up to 20 total) creates a new rift that always leads back to that original bound location. This makes it the better choice for building a home-return network — all rifts created with the same tool converge on a single destination.
Rift Tools
The Rift Blade
The Rift Blade is crafted at the Tesselating Loom using an Iron Sword and two Ender Pearls. It uses Iron tier stats (6 attack damage, equal to 3 hearts), has 100 durability, and is repaired with Stable Fabric rather than Iron Ingots. Its enchanted shimmer makes it stand out in the inventory. The blade has two special functions beyond melee combat.
Right-clicking a target within range teleports the player to that target's location, facing them. This is the teleport attack. This works on mobs, making the Rift Blade excellent for flanking Skeletons and repositioning during fights. Each use costs 1 durability. Right-clicking on the core of a Rift converts it into an active Dimensional Portal without needing a door, useful for quickly entering a rift in the field.
Rift Blade
Crafting Materials
The Tesselating Loom is the dedicated crafting station for all advanced dimensional crafting. It is built using Scaffolding, Black Fabric, World Thread, and a vanilla Loom. Once constructed, it unlocks every high-tier recipe in the mod and acts as both a standard crafting grid and a processing station for material conversion.
World Thread
The foundational crafting material. Obtained from dungeon chests and as a reward for closing Rifts with the Rift Remover. Four World Thread in the Tesselating Loom produce one Stable Fabric. World Thread is finite per dungeon run but replenishable through ongoing rift management, making it worth collecting every piece found.
Stable Fabric
The backbone material for dimensional crafting. Used in every Dimensional Door, the Rift Blade, Stabilized Rift Signature, Rift Pearl, and as the primary component of the Garment of Reality armor. Stable Fabric is also used to repair the Rift Blade.
Infrangible Fiber
Mined from blocks deep in Limbo using a Silk Touch pickaxe. This is the material that pushes progression into late-game territory, since reaching the correct depth in Limbo while avoiding Monoliths requires preparation. Four Infrangible Fibers craft into Enduring Fibers at the Tesselating Loom. Infrangible Fiber is also a component in Garment of Reality armor.
Frayed Filament and Liminal Lint
Frayed Filaments are obtained by detonating Unravelled Fabric blocks in Limbo with TNT or fire. A small explosion yields large quantities. Four Frayed Filaments craft into Liminal Lint at the Tesselating Loom, and Liminal Lint combined with a Fire Charge produces the Fuzzy Fireball, a novel projectile. Frayed Filaments are also tied to the Woven World Thread armor set.
Tesselating Loom and Core Materials
Armor Sets
Two armor sets are craftable at the Tesselating Loom. Both use dimensional materials and are not accessible until mid-to-late game. The Woven World Thread set uses World Thread as its main component. The Garment of Reality set uses Stable Fabric reinforced with Infrangible Fiber from deep in Limbo.
Garment of Reality Armor
Woven World Thread Armor
The Woven World Thread armor set currently provides no armor protection and is marked as a work in progress. It is worth crafting for cosmetic purposes and to complete the advancement tree, but do not rely on it for combat defense. The Garment of Reality set may have partial or full implementation depending on the version installed — check the in-game tooltip for current stats.
Fabric of Reality and Pocket Blocks
Fabric of Reality is the pitch-black block that forms the walls of all pocket dimensions. It absorbs all light, making it visually identical to the void when viewed from inside a pocket. Mining it requires a Silk Touch pickaxe; otherwise it drops nothing. It can be replaced by right-clicking with any normal block, which is how players redecorate their personal pocket interiors.
Fabric comes in several variants. Altered Fabric is Fabric of Reality dyed with any color using the colored Fabric recipes at a standard crafting table — the mod adds 16 colors plus black. Ancient Fabric is the indestructible bedrock-like material that surrounds older dungeon pockets. Unravelled Fabric makes up the terrain of Limbo. White Ancient Fabric appears in personal pocket dimensions as the entry-point material.
The mod also adds several dimensional blocks found inside dungeon rooms: Amalgam Block and Amalgam Ore contain Amalgam Lumps when mined. Clod and Clod Ore are found in dungeon terrain. Dark Sand, Driftwood wood variants, Gritty Stone, Decayed Block, and Solid Static all appear as structural materials in generated rooms and can be collected for building.
Advanced Items
Rift Pearl
Crafted at the Tesselating Loom using Stable Fabric and an Ender Pearl. The Rift Pearl functions similarly to an Ender Pearl but with dimensional properties, usable for interacting with rifts and portals.
Reality Sponge
Crafted at the Tesselating Loom in a 3x3 pattern alternating Stable Fabric and Infrangible Fiber. The Reality Sponge absorbs and clears pocket dimension structures, functioning as an area clearing tool for large-scale renovation of pocket spaces.
Fabric of Finality
The highest-tier material in the mod. Crafted at the Tesselating Loom using Enduring Fibers and Dragon Breath. Enduring Fibers require four Infrangible Fibers. Dragon Breath must be collected from the Ender Dragon in the End dimension. The Fabric of Finality represents the endpoint of the crafting progression.
Dimensional Eraser
Has 100 durability and is described in-game as erasing entities. Useful for cleaning up unwanted pocket dimension residents or entities stuck in dimensional spaces.
Music Discs
The mod adds three Music Discs found in dungeon chests: Creepy by Stevenrs11, They Stare Back by Firel, and White Void by Lachney. All three are atmospheric ambient tracks that fit the mod's unsettling tone.
Advanced Loom Recipes
Progression Path
The mod's progression is organic rather than gated, but it follows a natural arc. Early game focuses on exploring Gateways or crafting a Gold Dimensional Door to begin farming dungeon chests for World Thread. Mid game opens up once the Tesselating Loom is built and Stable Fabric is available — all tool recipes become accessible, and the personal pocket can be developed as a secure base.
Late game requires entering Limbo intentionally with Silk Touch tools to mine Infrangible Fiber. This unlocks the Garment of Reality armor, Enduring Fibers, and eventually the Fabric of Finality. Completing the full advancement tree requires entering every dimension type, setting spawn in a pocket, obtaining Fabric of Reality, and collecting World Thread and Infrangible Fiber.

FAQ
How do I get out of Limbo?
Travel downward to the lowest depths of Limbo, around Y 0 to 20, and find Eternal Fluid, the glowing liquid that pools at the bottom. Walk into it to be teleported back to the Overworld. You do not take fall damage in Limbo, so drop freely. Avoid looking at Monoliths on the way down. If one teleports you back up, just fall again.
Why is there a strange fractal shape floating in my world?
That is a Rift, formed when a Dimensional Door was broken without being properly closed. It will slowly grow over time. Use a Rift Stabilizer to stop its growth immediately, or a Rift Remover to close it entirely and collect World Thread as a reward. Do not leave rifts unattended, as they can spread across a significant area.
Can Monoliths be killed?
No. Monoliths are completely invulnerable. Attacking one with any weapon deals no damage and sets their aggro to maximum, guaranteeing an immediate teleport to Limbo. The only strategy is avoidance: break line of sight, move beyond 35 blocks, or retreat through a door before aggro reaches 250.
How do I get World Thread without running dungeons?
Use a Rift Remover on any Rift in the world. Each closing yields World Thread and costs 1 of the Rift Remover's 100 durability. Rifts form naturally in rare Rift Clusters and also whenever dimensional doors are broken carelessly. A player who never cleans up rifts can inadvertently build up a large supply of rift targets.
Is it safe to build a base in my personal pocket?
Yes, with one important caveat: do not use a Bed as a respawn point in the pocket dimension. Beds explode in non-Overworld dimensions. Use a Respawn Anchor charged with Glowstone instead. The pocket itself is completely isolated from Overworld events, cannot be griefed from outside, and persists indefinitely.
What does the Unstable Dimensional Door actually do?
It teleports the player to a random destination — another rift, another door, or directly to Limbo. The destination is entirely unpredictable. Using it once might be harmless. Using it repeatedly increases the odds of a Limbo arrival. It is crafted with an Eye of Ender rather than an Ender Pearl in the standard door recipe and is primarily a novelty item or last-resort tool.
