This ain't the best mod. I mostly made it for myself but I decided others may want another dimension mod.
This mod contains 3 resource dimensions.
Install JEI (Just Enough items) for help with Rune recipes
The Mines: Mining resources. This area has no mobs, but there may be cave spiders. This dimension is very easy to get lost in, be careful.
Infinite Plains: Building large structures, grinders, farms, etc. This is very helpful for mods like Pam's Harvestcraft.
The Forest: A Spooky forest for hunting hostile mobs. This dimension is very dangerous, enter at your own risk.
All portals are needed to be built like the Nether portal in order to work. Right click on the portals with the appropriate runes to ignite the portals.
Cave Dimension = Smooth stone portal frame
Farmland Dimension = Coarse dirt frame
Forest Dimension = Spruce wood frame
Dimensions may look strange with shaders. I cannot fix this.
This is NOT finished, and is roughly made. I'm not a professional mod creator.
