can’t simulate a normal cloth fx.
how does batman arkham do it? how does any game that is made with unreal professionally do it? and you guys who made the engine don’t bother? do i have to learn how to create clothing inorder to fix this issue or is someone gonna fix the cloth.
it looks terrible, acts terrible, un optimised as well PLUS, PLUS, it ruins the game.
i tried simulating with a rigged mesh, like cape thats rigged with joints, But i cant export the cape from the engine.
