Vertical Stacked Dimensions is an extremely useful mod that gives you a method to expand the world vertically. Therefore, there is no reason for you to ignore this mod in the process of playing the Minecraft game.
After installing this mod you will be able to get extended or almost infinite vertical build limit by applying only minimal modifications.
It can do that by stacking multiple dimensions on top of each other. Then, connecting them to ports moves you to the next dimension layers when touching the vertical border.
Obviously, this mod will affect ore creation for individual sizes. In addition, it can also add custom layers of arbitrary blocks to the space or even assume the position of certain sections at specific heights when creating the landscape.
Vertical Stacked Dimensions mod requires Minecraft Forge to work effectively.
