Imported tiled map from World Machine doesn't connect at tiled intersections

I just found a YOUTUBE video that clearly shows there is nothing we can do to prevent the immediatel POP in of terrain layers…only thing one could do per se is just to have a transport pad taking you to new level and new effects I suppose tohide the transition…dunno what I"ll wind up; with, but I do know it wont be FOG… ( unless I need it for foggy ENV)…

WHAT a shame there are no terrain LOD we could use to allow slowly loading distant terrain so its all visible, but uses very low TOD for distant terrain and switches as we draw near.
