Drawing an overlay mini-map

Question

alt text Hi guys, as you can see from the picture, I'm trying to make the red sphere(indicator) on the Mini map to follow the movement of the first person controller on the actual terrain. I've seen a lot of post on doing it, but i don't want to do it the "place a camera ontop of the actual terrain and change the settings etc". I'm asked to use another method which is to map the coordinates of the terrain to the mini map as you can see i circled in the picture. and then from there make the sphere(indicator) move with another script. I really need answers. Please help me. ):

alt text This is what I have currently when I click Play. All I need to do is make the red dot correspond to wherever the player went on the minimap. I did it this way because I was asked to make a minimap that shows the whole terrain and only wants the indicator to move. This was what I've been suggested. Or if you guys have a better solution which will not affect the performance to the VERY big terrain, it would be good to share with me. (: I hope this gives a clearer picture of what I'm doing. Real sorry for any confusion caused. Thanks for all the replies. Hope you guys can help me further. (:

The way i would do it would be to create a 2nd camera on top of the terrain like everyone else suggest it, but then i'd use a red sphere as a child to the player, that would only be renderable to that camera (through layer visibility). this way you don't have to calculate its position as a texture on the minimap :)

Edit: the 2nd camera would only render the red sphere, thus not having to render the whole terrain.
