Tree blurs out at an very short distance / halfly renderd. (Need help)

So I get it that a tree blurs out to get the system working better. But what's happening a car is gonna drive up to the house and alongside you see a number of trees. The problem is when you get close they just pop into details. This is how the trees look from far away enough.

And this is what it should look like:

I wanna have the trees in the picture below. Not that they snap into the half rendered trees like shown on top
Is there an way how to fix this?

 

They also dont produce shadows as shown here(the 2 back ones are not renderd):

 

Looks like a billboard LOD.
You should be able to increase the distance of the switch. Should be in the tree itself as a component.

 

You need to make the geometry double sided movie online , right now its only rendering from one side
