They said that if I succeeded, the result would be a monstrosity.
But I knew better than that. I knew what I had to do...
FOR SCIENCE!
Using an electromesenetic coil and specially designed crystals that pinch into the fourth dimension, I have created a device capable of harnessing the power of quantum entanglement to instantly transport matter across incredible distance, by generating an isomorphically entangled field inside the mese coils of two portals registered in a network!
BEHOLD!
The Mese Portal!

MUAHAHAHA!
So, who wants to step up and be the first one to travel using the power of electrons?
What?
Nobody?
Well, of course it's safe! I've sent my cat through loads of times!
What?
Oh, that's animal cruelty? Well, where do you think the leather for the seats in your expensive car that you always block my driveway with came from?
Well- clearly, none of you have any respect for scien-
OWW!
Who just threw a tomato at me?
Ugh!
I'll show you all, some day.
Just you wait...
Narratives and mad scientists aside, this mod adds fully functioning portals to minetest!
To craft them, though, you'll have to do quite a bit of digging.
Also worth noting, this mod is an overhaul of another mod made by RealBadAngel.
Recipes (for basic function):



This mod also adds remote control panels that can be linked (probably also using quantum entanglement) to any portal by simply right-clicking. Once linked, it can be used from anywhere by left-clicking, or placed down for anyone to access via right-click. Erwin Schrödinger is probably rolling in his grave!

Portals can be placed with the bottom embedded in a structure by sneaking while placing.
Portals can be accessed conveniently via a server-wide network, through a GUI which is available from any portal or remote controller.
Players can set a portal to "private" to hide it in the global network, making it only accessible to themselves and admins.
Speaking of admins, I've added some essential privilege functionality to the mod:
- A maximum number of portals allowed per-player can be set (msp_unlimited privilege and singleplayer bypass this)
- Players can access other players' public portals, but not change the description or public/private state, or break them.
- msp_admin grants full control of portals, including the ability to connect to an already active portal, see private portals, break other players' portals, and change their description or public/private state.
But enough talk! I need test subjects, so please!
