Black Lines between Game objects

7778-pic.png

You can see one of them in the picture above. They flash semi rapidly when character is moving. every one of the “cubes” below (the terrain) is a game object.

This is running in unity and has not been built.

Thanks

i had this issue whenI was working on a mini golf game… In the end we combined all the same ground type meshes using Mesh.CombineMeshes when we loaded the game.
