Tiled-Terrain Z-scaling breaks smooth tile-connection

importing a huge generated world (8x8 tiles) with 505x505 resolution each:

i’ve scaled the terrain hight (Z scale) by 600, to avoid my mountains being flatted out, but it seems to affect the

connection between tiles as you may see in the picture.

it is 100% smooth if i leave the scaling to be default (100,100,100).

how can i get rid of this thing?

thanks in advance :slight_smile:
