Omega Kits come in a variety of forms. Some of the older ones, and a couple of newer ones, like Niramyth, are a set of scripts that you drop into the mesh!
It's why we call all Omega System Kits, well.."Kits", rather then Huds. Some Kits use Relays which you wear all the time (like Maitreya and Catwa). Some use Installation huds that you wear and use one. (Like Slink and Belleza). And then some you have to get old school with and drag the mesh on the ground to put the script inside.
