Description
From the examples and tutorials it's vaguely implied that specular's alpha channel has some special meaning... e.g. http://sdformat.org/tutorials?tut=spec_materials (and not clamped to 0-1).
I'm assuming that is the object's **shininess** but it's not specified anywhere and as far as I can tell changing it has no affect on materials in gazebo.
Are we intended to not be able to adjust shininess without PBR or is this a missing spec, and possibly a regression in Gazebo?
