The new plug-in working nicely (and finally creates color manageable file nodes). 🙂

You can download it from Allegorithmic’s main download page:

Substance plugin for Maya section.

Two important advice:

1. If the texture connected through its Out Alpha output you have to turn on the Alpha is Luminance option.

   

2. As always, set the Color Space attribute correctly in every file node.
   sRGB: Diffuse Color, Specular Color etc.
   Raw: Roughness, Normal, Bump, Height, f0, IOR etc.
