Forest Telford created a simple masking method compared to the built-in generators.
I created this as a simple masking method compared to the built-in generators. Seems like most of them do too much or something too specific.
To use, simply add it too a mask as a generator. It will auto-plug in any maps baked out in painter, and will update if rebaked. It also has an additional normal map slot for passing in additional curvature info. Enjoy:)
In order to install it you just need to move the generator to the following folder: [User documents folder]Substance Painter 2shelfgenerators.
