This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i
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.
