Template:Shaderparam It defines a specular mask which affects how strongly each pixel of a material reflects light from the $envmap. The mask should be a grayscale image in which entirely reflective areas are white and entirely matte areas are black. For diffuse type specularity which does not rely on $envmap, see $phong.

Alternative methods
Rather than creating a whole new texture for a specular mask, you can embed one into the alpha channel of the $basetexture or $bumpmap. Model materials with $bumpmap must do this. Unfortunately, it won't reduce memory usage.
If you do use these commands, transformations and other such parameters applied to $basetexture / $bumpmap will also apply to the specular mask.

Merging Specular Level into Normal Alpha in 3ds Max
To merge a Specular Level map into the Normal Map alpha, you can create a Composite Map node with the normal map in Layer 1 and the specular map in Mask 1. Then right-click the composite map, click Render Map and save this new image to file (remembering to keep the Gamma at 1.0 and using 32 bits per pixel in the save options).
These steps are automated in the Alpha Spec tool in Wall Worm 2.72+.
