disable use pak file, and i found that the umap cost 221MB.
Pure DENIAL ! An empty project is always 153mb (with nothing inside!). And one year later, no answer at all, no tutorial, just links to other thread, where you can find zero solution… Ah yes, there is the mystical “blacklist.txt” solution, wich doesnt work (the empty project remains 153mb), wich you must be a soothsayer to use, because you cant find any tutorial…
