Also, am I allowed to make a port of the PBL to an app called skinseed? I will be creating a completely new palette for each season and it will be invite only. The judges and owners of PBL from here can moderate it and help/restrict it. I hope you grant the permission
Paint.net and then conversion of transparency with gimp (for mac) Paint is easier for starting, I actually used Procreate for iOS to create a wonderful texture pack, but it doesn't support transparency either.
