Blur?

I was able to fix 2 bug that my system had in the lock target system. Also, I made in such a way that, when the lock target its on, the field of whew change, making the camera a lot more focused on the enemy. I think next step it is to create some kinda of blur effect. Also I create a brush in the UDK editor, as reference to build up my stairs in maya. I ve exported the brush trough fbx, which is pretty cool.
