How i can apply a specular map in Wings3D?

[micheus]

Ok, it does not display spec. maps at the moment but can it still apply?
I will export the model anyway and it will go into games. (which games display spec. maps)

It can't anyway.
You can assign maps to diffuse, glossy, bump and normal maps.
Maybe you could use the map you assign to glossy to be assigned to specular in the engine?!
They are not the same, but seems to be related.
