Using heightmap seems to create seams.
I'm trying to build an island from a heightmap and then generate noise on it and I'm getting really noticeable seams between tiles. This doesn't seem to happen when I'm not using the heightmap. I'm not sure if I'm doing something wrong, I didn't notice it until after I started adding a locked zone (which is not falling on more than one tile. All of the tiles, not just the one with the locked zone or tiles around it are affected.
Appreciate your help trying to figure this out.
