[Help] View Distance

Hi

I have a problem with the view distance. When I edit at some points the heigth I cant see it ... I have to move really close to see the changes .. May someone can help me.

Here are 2 screenshots

First: I edited the terrain and I cant see something


Second: I moved closer to the position where I edited and now I can see the changes


But now what I have to change to have a far view? I tried to set the farviewclipdistance on something far, not helped ...

Greetings
