First of all sorry about the lag and the sound(Terrible Quality). Anyways, after several requests I felt like making a video on how to make a simple minimap. This is not a beginner tutorial, if you are completely new to Unity or just learning Unity you may want to check out for things that you don't understand. 3D Buzz has a tons of FREE Unity videos, also many others.
This tutorial requires basic shader understanding, and Unity Pro. I was going fast in the video to record the video in a short time. Hope you guys liked it, if you have any questions, pm me or just write a comment :)
