Best method for bulk importing obj and setting up textures

If I have hundreds of objs to import, what is best way to set up Iray Uber shader textures?
I can edit the .mtl file texture references, but not sure what is the mtl key (e.g., Ka, Kd, Ns) to define the following iRay Uber shader properties:
- Metallacity
- Diffuse/Base Color
- Translucency Color
- Specular
- Roughness
- Bump
- Normal
- Opacitty
Related question: is there a way to invert textures in bulk within Daz image editor or is it best to do that in batch image editor (like ImageJ) before importing textures?

Kd is diffuse, Ka is ambient I think (which isn't really used, unless you use it for emission), Ks (which you don't mention) is specular (so could be used in specular of glossy properties), and Ns is the specular exponent (I can't recall what that is for). The MTL file is very limited in the atributes it supports. Daz studio will assing the Iray Uber Base shader to OBJs imported while Iray is the active render engine.
