I am currently playing around with World Creator 2 BETA stand alone and over the last month as it is approaching the RC build I can say that it’s really coming together well. WC2 -> UE4 workflow has improved dramatically now that we can directly export heatmaps of the terrain for each texture applied. These maps import directly into your terrain layers without modification.
Tiling will be available soon for large terrain but until then I tried a repeating terrain using 1kmx1km tiles and set it up to import 6 by 2 grid in world composition to test out landscape LOD and it jut worked. Seeing mountains far away go from static mesh to landscape was great.
They have been saying that “tiling will be available soon” since the first announcement. I am beginning to believe that that absolutely necessary feature will never show up.
