I would take that dark border out then, I interpreted it first as a mistake by your tool, like it was doing something funky to the layer mask or something. Also I think the saying is "bear in mind", as in "bringing something to bear" or "bear with me."
Oh, nevermind that ,it is OK :) A more perfect solution is to rework the action so it uses a clean black and white render of the UVs as a base for the layer masks. Such texture could be easily created using TexTools Another possible solution is to add a layer style with "inner glow" set to the default normal map color…
