Cosmos Portals
Long treks to the End Portal and messy Nether hubs are a familiar part of Minecraft, but they do not have to be. Cosmos Portals is a mod that lets you build a portal to any dimension you have already visited, and even between two points in the same dimension. If you have ever wanted a clean, direct route to your far-off base or a shortcut to the End, this mod delivers exactly that.
What Cosmos Portals Does
The core idea is simple: once you can reach a dimension, you can link a portal to it. That means no more covering thousands of blocks on foot or building sprawling Nether tunnels just to move around. You place a portal, connect it to a destination, and step through. The same system works for travel within a single dimension, which turns long-distance logistics into a short walk.
Cosmos Portals for Minecraft is part of The Cosmos Series and requires Cosmos Library to function. Make sure the library is installed alongside the mod, or nothing will load correctly.
Supported Versions and Loader
Cosmos Portals is now available for Minecraft 1.21.1 on NeoForge. As of version 8.11.0.0 for 1.21.1, the mod moved away from native 32x textures in favor of 16x textures, so it blends more naturally into vanilla Minecraft's look and feel. If you prefer the original 32x style, or you already run other 32x resource packs, those textures are still available as a separate resource pack.
Texture Options at a Glance
- Default: 16x textures that match vanilla Minecraft
- Optional: original 32x textures via a separate resource pack
- Both options work on Minecraft 1.21.1 with NeoForge
Key Features
Beyond basic portal creation, Cosmos Portals adds a solid set of tools for organizing and controlling your network.
- Customization: give each Dimension Container its own name and color so you can tell them apart at a glance
- Portal Dock [4]: stores four Dimension Containers and lets you hot swap between them using the GUI or a Dock Controller Block
- Portal Dock [8]: the same concept with eight slots for larger networks
- Dock Controller: a block you link to a Portal Dock, letting you switch stored containers with a single button press
- Portal Filtering: restrict portals to specific entities, enabling player-only, mob-only, or even item-only portals
Portal Filtering is especially useful on servers. You can build a private route for yourself, keep mobs from wandering into your base, or set up a dedicated item transport line without extra machinery.
How to Install Cosmos Portals
Getting started is straightforward if you follow the right order.
- Install NeoForge for Minecraft 1.21.1
- Place Cosmos Library in your mods folder first
- Add Cosmos Portals to the same mods folder
- Launch the game and confirm both mods load without errors
If you want to skip the manual file juggling, the foxygame.net launcher handles the whole process for you, pairing Cosmos Portals with the correct Cosmos Library build in a single click and keeping both updated automatically. When you download Cosmos Portals, always match the mod version to your Minecraft version, since mixing builds is the most common cause of crashes on startup.
Building Your First Portal
Step 1: Visit the Destination
You cannot link to a dimension you have never entered. Travel to the Nether, the End, or any modded dimension once so the mod can register it as a valid target.
Step 2: Create a Dimension Container
Craft a Dimension Container and assign it your chosen destination, name, and color. This container is what the portal reads when you step through.
Step 3: Set Up a Portal Dock
For a single destination, a basic setup is enough. Once you start juggling multiple locations, upgrade to a Portal Dock [4] or [8] and link a Dock Controller so you can swap destinations instantly instead of rebuilding portals.
Final Thoughts
Cosmos Portals solves a problem every long-term Minecraft world runs into: travel takes too long. By letting you build portals to any dimension you have unlocked, and by adding docks, controllers, and entity filtering on top, it turns a simple shortcut into a full travel system. Whether you are running a small survival world or a busy server, it is a clean, well-integrated addition worth trying on Minecraft 1.21.1 with NeoForge.
