The skin archives must remain with the same size and data layout as the originals, or they won't work. So the minimum/maximum number of skins possible is the same... however many skins were in the archive to begin with. You cannot add and remove skins. You can only replace them.Thank you for the reply, what if we just had a pack with existing “Real” one, would that work? Do the pack have to have a minimum number of skin?
But Reiza have said they are already working on an official skin creator, so it sounds like we will have full skin editing features one day soon.
