This mod adds easy transportation between 2 (or 3 or 4) portals based on what material they are made out of or the color. So you could create a blue wool portal in your house that easily connects to another blue wool portal deep in your mine. And on top of that you can then go from your mine to a portal in the nether that also then leads back to your house. It can be as simple or as complicated as you like. And you can have as many portals as you want of any different color that all travel to different destinations.
In order to make the portals you first need a bucket of Colorful water and to get that it takes a couple of steps. You’ll need 3 iron ingots and a gold ingot to make the ‘Almost Stain Proof Bucket’. Then fill that bucket with each of the dyes. Finally right click that ‘Bucket of Dyes’ and you have your ‘Bucket of Colorful Water’.
The best thing about this mod is you can make a portal of almost any shape so long as it doesn’t exceed 16 blocks from the placement of the colorful water and is a closed loop. Even better is you can create a single block portal that you can take with you in your inventory and place wherever necessary.
