Radar Map Blip..........................

Hello all, in my project I am trying to make a radar, not unlike the one in GTA. I attached a plane with a material so that it only shows up on one of my Cameras i.e the Radar cam.

The problem I am having now is that obviously it rotates with the object, I tried unparenting it but then I can't destroy it without destroying all the others.

Sorry if this is a bit vague, and suggestions would be great.

Thanks
