This course contains a little bit of everything with modeling, UVing, texturing and dynamics in Maya, as well as compositing multilayered EXR's in Photoshop.
a mirror material is made of 2 different material, one to cast reflection and another one (a zinc plate to absorb light)
so this is my set up for a mirror. u might get away with simpler method, depending on what u want to acheive...
so for instance, if u have a primitive cube, u put the zinc plate on a face behind the face containing the mirror shader.
p.s. as with a real mirror, if light is casting right in front of it, it will be bright, so ur light source need to be coming from behind it for best results.
