After I render with motion blur my file seems to change, and the motion blur is barely noticeable (almost as if it's behind my object?) Before rendering things were looking great in my picture viewer. Then I go to render and the motion blur is barely noticeable. I read that there is some difference between what you see in the picture viewer and your final render, but this is not that... After rendering, and touching absolutely none of my settings, I went back into my picture viewer and the render was suddenly coming out just like in the final render. I tried this entire process over (reopening up an earlier version) and the same thing happens. The motion blur changes after being rendered. Why would this be happening? Help please asap!
