I am making a Black & white globe. I have mapped the texture to the poly globe. I would like bit of roughness on the surface. I embossed my texture in PS so all the continents do look raised above sea level but inside the continents everythin is flat. I would like some unevenness in the surface.

II- My sea is dark grey and the continents are light grey. Is there any way I can make the continents chrome without pysically modeling the continents????
