A new Bryce 7.1 pro render using the unrated power of Bryce trees. I must admit that they're always good for distant render (in this case).
About 4200 procedural trees and 4 billions polygons. The entire scene is taking only 900 mb in memory usage which is not that much.
Bran castle in the center of the scene is a free model from sketchfab.
Rendering time about 8 hours due to the fog slab and leaves transparency.
