What controls default material's "Ns" value in exported .obj files?

If I export a Cheetah3D file to .obj format, the generated .mtl (materials) file starts with a block like this:

newmtl default
Ns 64
Kd 0.700 0.700 0.700
Ks 1.000 1.000 1.000
Ka 0.700 0.700 0.700


The color values seem to come from the "Colors" panel in the "Preferences" dialog, but I cannot seem to find where the default value of 64 for the "Ns" parameter is defined. Does anyone know? Perhaps it's hardcoded in Cheetah3D?

Yes. Sorry. Typo in the subject (now fixed.) I'm familiar with what the value does if a material is defined, but I was asking what controls the values for the "default" material. That is, the material used when no specific material is defined.
