Specular/Metallic is not working in standard shader?

I recently downloaded and upgraded to Unity 5 to test out the standard shader for myself and when I try to mess with the Specular/Metallic settings, the sphere only turns black instead of it turning shiny and reflective. What am I doing wrong here? I have attached two pictures to show what I mean.

The things I have tried were to:

  1. Put a skybox in the scene (Had no effect)
  2. Make the shader transparent instead of opaque (Only made the problem transparent)

The specularity gave me headaches as well, until I figured out the small bit of information easily missed:

In the specular map (map you upload under Standard/Spec Setup), the specilarity is determined by the Alpha, not by color.

Easily fixed by going to your texture you are using as specular map, and ticking “Alpha from Grayscale”, “Apply”.

I had the same problem like your pics… i know it’s old but it might help someone

it seemed that i’ve putted the reflection intensity to 0 in the lighting tab and that affected the specular material
making it anything between 0-1 will solve this
