Need help ripping models from Epic's new game Fortnite.

Using ninja ripper, whenever I go into game and hit f10, I get what looks to be a spherical mash-up of random polygons from whatever 3D model I want to rip. Any help would be nice.

Isn’t this game on unreal engine 4? you can get models out with original rigging

How? I am fairly new to this entire process. I’m trying to use ninja ripper to get the model out, but If there was a simpler way I’d be very happy.
