I am a newbie with World Machine. I tried to find answers but couldnt find one. I am trying to do a generate a linear tileable terrain and so I was able to create 2 heightmaps x0 y1 / y2 and y3. When I use theses heightmaps in my 3d package tool and put the tiles next to each other, there are far from being seamless. I was not able to place/rotate correctly the maps to make them unified/seamless. Any leads?
