Unfortunately it looks like I'm stuck at the same place that other anon was back when the game first hit EA - with meshes but little/no textures. Seems to be an issue with a lot of unreal 5 games at the moment, they apparently use "virtual textures" for most things instead of normal ones, which current tools aren't able to extract. I know next to nothing about unreal engine so I'm not sure how hard it'll be to get there, but since it isn't just an issue for this game I'm sure someone will get it working eventually

If anyone is curious, everything I know comes from this forum post
