My Sun is Sationary. And Builded.
I have 1 UV. I Have a Normal, Displacement, occlusion and 2 Textures. 1 Texture for the Tree, and one Texture for effekts (emessiv) on the Trees, like a blitz with Alpha Channel.
When I look at the shadows on the ground, then the tree is normal to see. When I look at the tree, then the shadow is black immediately.
If i use Skylight as Movable, its look good.
