Okay, thanks all.

But my problem is not the size of the castle-windows or the blending,  this was just a fast mask in AfterEffects for testing. Also the castle is stupid - i write above: ...final to build burning cottages at the left site on the footage. All others are TESTS.

When you take a look at the picture of Cherryman - i get this results too. But this are not realistic.

Again: My problem is a describe above - how to get **natural Trees, Grass and Rocks.

What is the important settings and light for results like this VUE 6 example.**
