Fresnel Ramp question

[Mach3DS]

Does the fresnel control the angle of the specular alpha in addition to the diffuse alpha?

[Bjoern]

Fresnels can influence, specular maps, reflection from diffuse map alphas and bump maps, but this has to be set by the developer for each material.
Open the model in question in ModelConverterX and check the material settings to see which options have been set.
