Ok so I have 4 raw files and I import them in and add them to a master level through world composition . and Here is what happens
They are lined up perfectly in the levels map, I need them to be seamed together yet they are not. I dont know how to convert the raw files to tiled landscape heightmaps or I would do it that way. This is a big land and an expensive one so I have to have a fix for this but I can not figure it out at all I tried it in 4.7.6 and 4./8 preview build. also when i smooth or scupt the land it pops the seams up
