Cosmos Portals

Notices

Cosmos Portals is now available for 1.21.1 and NeoForge.

As of 1.21.1 version 8.11.0.0 Cosmos Portals has moved away from native 32x textures, in favor of 16x textures to integrate into the look and feel of Minecraft better. For those who prefer 32x textures or run other 32x Resource Packs, the original textures are available in the form of a separate Resource Pack.

Description

Cosmos Portals is a simple mod that allows you to create Portals to any Dimension, so long as you can visit that Dimension first. You can even use it to travel between places in the same Dimension! No more messy Nether Portals, or having to cover long distances to your End Portal, travel exactly where you want!

New Features:

  • Customization: Choose your own name & colour for your Dimension Containers.
  • Upgraded Portal Dock [4]: A Portal Dock that can store 4 different Dimension Containers with the ability to hot swap them either using the GUI or the Dock Controller Block.
  • Upgraded Portal Dock [8]: Same as the above but with 8 slots for Dimension Containers.
  • Dock Controller: A block which can be linked to a Portal Dock and switch between stored Containers with a simple button press.
  • Portal Filtering: Filter portals for specific entities, allowing player-only portals, mob-only portals or even item-only portals!

32x Resource Pack
