HexxyPlanes

Have you ever felt that a hollow obsidian cube beneath the very ground upon which you walk just isn’t quite secure enough for your valuables, goodies, and trinkets of various shapes, sizes, and lustres? Well how about a nigh impenetrable¹ and almost certainly unique² plane of existence that only you³ have the key to?

Welcome to HexxyPlanes, an addon for Hex Casting that provides you with your very own 14 by 14 by 14 cube for your use. With nothing more than a flick or two of your staff, you can be transported to a cell in which you can do whatever you so desire:

• Hide your stuff!
• Cast some spells!
• Farm crops!
• Enact entirely ethical experiments on your local villager population!
• Make a private lounge!

These possibilities and any more that you can come up with (that fit within the footprint of the plane) are possible. The wall’s the limit!

¹HexxyPlanes does not take responsibility for absurd contraptions that warp reality allowing access to your plane.

²There are 263k possible cells one could get, the odds of a collision are slim, but never zero.

³You can share, I won’t stop you.

A Note on Oneironaut interop:

In order to use Oneironaut with this mod you must use the most recent version present in the Hexxy4 modpack repo, or the version present on the github repo (direct download links to Oneironaut JAR files). The file downloaded by the current version of the PackWiz file as of 12/22/2025 _will not work_.

Issues pertaining to a NoClassDefFoundError will not be handled unless you show that you have gotten the most recent version from either of the linked locations.
