Hi,
Thanks for the quick reply, unfortunately I can send the file since everything is owned by the office that I worked for, on their server and also I'm bound by a non disclosure agreement regarding any files, that is the reason why I sent only a small corner of the rendering, is the most that I'm allowed to send. What I can do is send you all the settings that I use. (V-Ray scene settings, materials used, lights settings, and Forest Pack scatter settings.
Let me know what you think.
