Awsome I like the valley the most as well Do you use a fur shader for the grass and static shadowmaps? Where did you find an article about such great fur :P I failed with my own tries to realize something similar until now . The Volumetric particles are cool as well as all the other stuff :P
Valley scene looks amazing. Abaut shadows - I'em verry impressed. What you use for tree shadows. I see tree drops shadow on terrain and also on models. Mayube i missed something but did is possibly make dynamic shadows in A7 Comm? In my example best way is paint my tree shadows on terrain skin or shadowmaps
