hello i got no succes in baking specular in blender. and the full render do not show the specular neither. is there some actual limitation?
Can you show the result you get and material settings and textures applied to it? And do you bake with blender internal or cycles?
Attached is an example blend file to bake the specular intensity and specular colour maps
