actually i just figuered out how it works a little you need your base mesh into maya and make a lot of other meshes for some facial poses (i prefer making them in zbrush ) and for everyone make a different texture for everyone they export all your meshes into maya select all of them and lastely select your base mesh and (annimation-> deformers->blendshapes) then you can make some facial rigs like that and if you really want the same tool you need some programming skill to append each blendshape for a certain topology in an image … and that’s it
