Landscape Material with some shadow

[DeadOpsHD]

I’m writing here because something wrong in my landscape texture.
My texture look murky and i don’t know why this happen.
So take a look at this two pictures :

• The first picture is my photorealistic texture with a point light : Screenshot by Lightshot
• The second picture is this texture with directional light and you can see some shadows : Screenshot by Lightshot

i’m beginning in unreal engine 4. So, please don’t be agressive.
Any help is welcome.
PS : I’m sorry for my bad english. If i’m making some grammatical mistake please tell me because I’m learning the english too.

Cordially,
DeadOps

Are you using parallax or displacement or really extreme normal maps in your material? Looks almost as the leaves are causing the shadows. Maybe try a simple material on a static mesh first to make sure the material’s node setup is working.
