An additional feature would be great to the motion blur control to adjust the length of the blur "Shutter angle". Right now it is impossible to control it specially if you have an animated car and you need to control the blur in some scenes. I am doing few tests right now on an animation and I see that sometimes the blur is a bit too much and can't be reduced since it is set to a fixed value. I think this should be an easy feature to add if I am not wrong :)
Thanks!
