Currently, brush alphas can manually be imported and set up with identical brush settings inside of 3DO.
Brush alphas can be imported by clicking the 'Import Category' button in the Brushes menu and selecting your folder with brush alphas. This category shows up in the Brush selector tabs with the same name as the folder. At the moment the brushes need to be in JPG format, but we are working on ABR support as well!

Looking forward to ABR support.
