This repository contains height maps to toy around with. The height maps were created for prototyping in Unity within a few minutes using World Creator 2. You may as well use them in UE4.
For your convenience I suggest to use the World Creator 2 Sync-Tool. It's free. Just go to the World Creator 2 website and hit the Download button and download the "Sync-Tool" for your development environment. It's very easy to use. In Unity open the tool via Window -> World Creator Sync Tool, select the sync tool xml file and click the Synchronize button.
The height maps were needed for toying around with Vegetation Studio Pro and the Meadow Environment - Dynamic Nature assets in Unity:
I thought I'd share them in case anyone else wants to toy around. You can find preview screenshots in the folders of the height maps.
