Stitching two or more terrains...

There are a few assets those help stitching terrains to one single big terrain.

But there are some small gaps between terrains. Even tho their corner’s height map data is the same.

Have anyone faced this issue? How can i handle it?

It makes my game cheappy…QQ…

There are terrain tools for doing this and much more in the Asset Store, well worth the investment.
