Problem with terrain

Hello,

this is what comes up when i import/create terrain,

as u can see on the picture, there are places on the terrain where the mesh is not fully connected

u can see thru these gaps, also i have a bad flickering in the distance on different parts of the landscape

what is wrong with that?

greets

Another shot of the problem:

Please help!

world machine?

I think the world machine blend with tiled terrains is not set to 100% you need to set it to 100

what do you mean with world machine?

i imported a height-map created in pshot with this result,

then i tried the internal landscape creation tool, that comes with the editor,

but its still a broken terrain-mesh
