My Landscape/Enviroment wip (heavenly inspired by The Witcher 3 demo videos)

Not much to show since my last post. Worked on my terrain material a lot, tryed to add height blending instead of a normal map for blending betwen layers but dont get it to work nicely. Since all my layers are slope based the material grows fast and i simply cant oversee it with my little knowlege of shaders.

And i made a little foliage test with some old 3dmotive tutorial trees and bushes. They are quite lowpoly but mit fps drops from 80 to 30 in imersive mode. Hope there is some love for foliage in 4.6.
Foliage Material is super simple. Only thing i did to get rid of the dark backfaces is to plug the texture divided by 10 in the emissive too. Normals are tangend space.
