Sorry Jojo, Zombies don’t interest me, not even remotely so i don’t bother checking what’s out there. I’m glad to humor you though.
Yea I’d say that could totally be a looping alembic import, but i think it can also be straight out cloth with some subtle wind. It looks simple enough for that. The folds could be a material offset coupled with some normal maps, since cloth sim in UE will most likely flatten out the geometry during sim.
