The one I use is called "simwide Teleporter". It's easy, simple and I believe it's free AND transferable. All you do is set one down, move it where you want it, got to edit, change the name of the object to whatever destination point it is specifically (I.e., "beach", "house", "club", "3rd floor", etc.), then you can change the texture and glow if you want, to better blend in. Then, do that however many times, properly naming each teleport pad, then you're done. They automatically connect with each other and pop up on a blue side menu. You can set them to public, group, owner, etc. And, when you click the pad, the base, you pick your destination point from that blue menu. Then, a green orb pops up, click it, done
Hope you find it! I'll look up the exact name when I get inworld.
