I have the color texture connected to the diffuse and the alpha channel, of it, to specular. Normal map texture to normal. And another texture ( black and yellow for the part that I whant to "shine") connected to the emissive.
here is a link with the connections in the material editor http://www.facebook.com/photo.php?fbid=2448358329383&set=a.2448356529338.2109028.1264707747&type=3&theater
how are you connecting your emmsive map? a texture map can olny provide vales between 0 and 1, so to push it over you multiply it by a constant above 1.
