new Titanic ship asset

I know what everyone be thinking reading this, I saw a asset on you tube, a titanic and the name UE4, and I had a looksy you tube guided tour through the Titanic I don’t know how he did it, it was awesome an exact replacer of the ship, I was wondering when will that become available on the marketplace ive seen many of a you tube on UE4 but no release date, im telling ya all Titanic looks equisite.

I was wondering what program did they use to craft the titanic, was it done on UE4 or Blender, or some other mysterious program.
