Hey Guys,

In other words:

I want my camera just about some meters away from the stone wall (terrain), but it always looks, as if the camera is 1000m away - because of the little structures and the big amount of detail. I don't need so much detail, when my cam is 1 m near the ground (except little stones and something like this) - it more has to be more flat, but with hard crips edges, but not so structured like a big terrain.

so that it looks more like this:
