Portals & Dimensions
No reviews yet
Create custom portals with configurable frames and linked custom dimensions. Build dimensions with math formula terrain, vanilla noise, or flat/void worlds.
Includes a large focus on traversing worlds with enhanced world generation, structures, dungeons, and more for players to find unique loot.
General improvements to world generation, such as bug fixes, aesthetic overhauls, or misc additions.
Fabric is a mod loader for versions 1.14+ of Minecraft, particularly popular for client side and optimization mods.

Description
Portals & Dimensions
Create fully customizable portals linked to procedurally generated dimensions — all from an intuitive in-game GUI.
Features
Custom Portals
- Build portal frames from any solid block (obsidian, diamond, gold, etc.)
- Adjustable portal size (width x height)
- Configurable 24-bit portal color with live preview
- Horizontal and vertical portal orientations
- Color picker with palette, recent colors, and RGB input
Custom Dimensions
- 7 terrain types: Void, Flat, Normal, Amplified, Nether, End, and Math formula
- Math terrain: Define terrain with
sin,cos,noise,perlin,fbm, and custom expressions - supports 2D heightmap and full 3D density - Coordinate scale slider for terrain stretch/compression
- Smooth terrain toggle for natural-looking slopes
- Configurable sea level, surface/underground/fluid blocks
- Cave generation with adjustable density
- Ore generation (coal, iron, copper, gold, redstone, diamond, lapis)
- Structure generation (villages, temples, etc.) - toggleable
- Mixed biome support with Perlin-noise-based transitions
Atmosphere
- Sky, fog, ambient light, water, and cloud color customization
- Fog density control
- Skylight, ceiling, and ultrawarm dimension properties
- Light level override (0-15)
- Configurable ambient particles (portal, end rod, soul fire, lava, etc.)
Game Rules (per-dimension)
- Day/night cycle & fixed time
- Mob spawning, natural spawning, PvP, fall damage, fire spread
- Keep inventory, bed works, respawn allowed
- Weather lock (clear, rain, thunder)
- Gravity multiplier

Math Formula Terrain
| Category | Example | Description |
|---|---|---|
| 2D Basic | sin(x/10)*cos(z/10)*20 + 50 |
Rolling hills |
| 2D Intermediate | noise(x/20,z/20)*30 + 60 |
Smooth noise terrain |
| 2D Advanced | fbm(x/40,z/40,4,2,0.5)*40 + 50 |
Fractal mountains |
| 3D | fbm(x/30,y/15,z/30,3,2,0.5) > 0.5 |
Floating islands / caves |
| Beginner | abs(x/10) + abs(z/10) * 2 + 40 |
Valley |
Available functions: sin, cos, tan, abs, sqrt, pow, min, max, mod, floor, ceil, round, noise(x,z), perlin(x,y,z), fbm(x,y,z,octaves,lacunarity,gain), if(cond, a, b), random(x,z), dist(x,z), gauss(x,z), mix(a,b,t), remap(v, inLo, inHi, outLo, outHi)
Requirements
- Minecraft 26.1.x
- Fabric Loader 0.18.5+
- Fabric API 0.145.3+
Getting Started
- Craft or get the Portals & Dimensions lighter (creative tab or
/give) - Right-click to open the configuration GUI
- Portals tab: Set frame block, portal color, and size
- Dimension tab: Configure terrain type, formula, biome, colors, and game rules
- Manage tab: Save, clone, export, or import dimension configs
- Light a portal frame with the configured lighter to create a linked portal
