A lead to UE4 landscape automation.

Ok, this is my quick notes for UE4 as a blog.
Currently, i'm working on stuff related to automatic terrain generation. When dealing with large amount of data, something like manually clicking editor import to create each landscape is not an option.
To automate this:
The first lead is inside: LandscapeEditorDetailCustomization_NewLandscape.cpp
FLandscapeEditorDetailCustomization_NewLandscape::OnCreateButtonClicked()
This little method will show how we can spawn a landscape out of nowhere, creating a landscape from a raw data. Cool, so now we can procedurally generate landscapes here in the editor.
