I am very interesed in this, but i would like to say something related to that, as far i know we only get the brushtip from Photoshop Abr. files, at this point somebody made something similar but in an asking way why it cant be posible to do that external or 80-90% of sucess.
This is something have been discussed in many ways, but i believed there is a solution could be done if more people are intereset in this, starting with seeing the example how Procrate engine could be done a good example how they import abr brushes they can do that too. https://folio.procreate.art/discussions/7/25/24149
At this moment there is not answer to do that for the moment.
