Wolrd Machine to UE4 using World Composition

Alright, I updated the first post. It was a fairly simple fix. Instead of using landscape layer weights, use landscape layer blend nodes. You will only need one node. Then in the node properties and each layer to the elements and label it to match your weights. Hope that works for you. I just tested in 4.8.1 with no issues. You will have to play around with the scaling to get it perfect.
