we get a thread like this every month or so, mostly with the same reasoning. (Honestly HOW does someone lose all their source art?). even if you do unpack it, you will only get the art. blueprints/levels/settings/WhatHaveYou, cant be reconstructed. i have played around with most of the tools that allow unpacking (was a TA for 2 years and we had to verify students were not using other peoples assets). nothing of the “Project” could be recovered, just the art.
