The good news is that I found solutions for two of my major problems.
The first is how to re-scale the Z from UE, because you don’t like the resulted height after you Load your tiles:
- Select you LandscapeProxies from the World Outliner, all of them! Go to Modes->Landscape. Without doing anything further here, check your Details window, because under Transform all your Settings became available, even though your Landscape Proxies which you selected earlier became deselected. Do not try to select them again, just simply set your Z value to another. It is imperative to have all your Proxies selected first, otherwise you will mess up your Z applying it just to some…
The second and biggest issue, the fact that your imported landscape is flipped on X.
- Select again ALL your Landscape Proxies, then right click, select Transform->Mirror X. Depending on the terrain size, you will wait a while, but it will solve your problem
Hope this helps…
