This a port of the V2 of the following mod: https://www.nexusmods.com/skyrim/mods/23471
This mod Adds stargates to skyrim, see screenshots for a better idea.
UMP1R3 gave blanket permission to use anything from his mod.

Changes from oldrim version:
Originally his mod was an ESM file, which CK won't allow to modify an esm so I copied it all to an esp instead.
Updated all the stargate meshes using NifOptimizer 
Saved the plugin in form 44 and in doing so corrected the floating building bug found when using the f43 original mod.
I also deleted the wild edit I had made in order to save the esp using SSEedit
Bare in mind this mod adds a fort like structure near the Rift Watchtower so if you have another mod editing the same place you will likely have conflicts.
The lift to the underground base in the SGC is quite something.
I also took it upon myself to export the facegen data for all the imperial npcs added by the mod.
CK gave me warning that the scripts were not attached to anything so just so you know whilst the gate will animate chevrons and spin the activator for actually using the gate is non functional so a re-write of the script might be necessary.

I'm uploading this to get the ball rolling for a proper stargate mod with quests new world spaces etc...
I will likely be using this as the basis for a future mod of my own

I'm uploading this as modder's resource just as UMP1R3 did , this is not a finished mod
