How do I add a teleport location to a map without one?

[webman]

I know how to add the teleporter npc to the map, but what I need to know is how do I add the teleporter graphic? The actual portal to the map, not just the npc?

The portal the npc stands on with the spinning thing on the top is what I need to add to a map. Is it hard to do?

Example, I want to add one to the doomed maze.

the blue portals are map data so u can't add more like them.
the best way like i did is to duplicate the red portals, you can change the color if u want and add them as npc , just delete the name.
and then all u need to add is warp.csv and location.csv lines

Thanks. I guess I'll add red portals then and put a teleporter npc in front of it.
