Blur problem in render

[asaghostwip]

Hi everyone,

I just start to work with Vray in softimage 2012 and I have some trouble I can't resolve (I try to search in many differents forum but it seems i m the only one to have this problem !)

 

All my textures appears correctly in foreground but after 1/3 of the picture, it becomes bluury and I don't understand why ?

 

So, it will be soooo appreciated if someone get an idea about that problem. I have to make this project in four days with lot of trees so I can't do it with mental ray.

 

Please have a look on attached pictures, render and settings (and excuse me if my english is not correct!)
