Thanks for your answer, but that doesn't work.
I found the error on my own.
It was this part of code i forgot:
Code:

Hi Akilan,
thank you, than your question is my question too :)
My thoughts:
I don't know if osg already provides a fading node to fade in/out the
subsequent scenegraph.
If not, maybe you should develop one. This node could be used in your
osgTerrain to introduce fading in the LOD mechanism.
