I've recived a message from Oriceles and he said by sharing a message on twitter you can get those resources. I followed the way and I am asking here. But is it legal to use those resource pack in a non-commercial project while this bonus is not longer available?
It is worth noting that many nonRTP portraits are frankened from either the VX or ACE pre-order bonus portrait sets, but few are posted with terms specifying that they are available only to users of a certain maker. Just saying.
