LOD and Trees

Hi Guys

I've just started working with Unity and am now about to use the Tree-Tool within the Terrain creator in unity. I have a question regarding the switching between the LOD- and the full res models of the trees. Please check the attached screenshot.

First: The switching border, where the LOD model transforms to the full res trees, is now very hard. Unfortunately cranking up the value in "fade length" in the terrain settings doesn't really help. The trees are still being "switched" instead of "faded" from one to the other. Is there a way to make this switching softer?
Second: As you can see the LOD trees are much brighter as the full res trees. Is there any possibility to correct this manually?If so, then the first point wouldn't be so important anymore.

I'm grateful for every advice you can give me

Thanks and best regards from the Unity-Newbie

advice - get speedtree =)

 

Looks good! Thanks

 

Okay, that's nice! But now, when I paint the trees on my terrain, it's always painting the same tree-model, though I have a variation of 7 trees imported in the tree painting tool. I have to select an other model that this one is painted.
Is there a way to scramble this?

 

Nothing?
