Loving the amplify motion effect so far, however I was wondering if it's possible to disable the blur effect in the following case. I'm using a custom silhouette shader (similar to the one here, but... simplier) and unfortunately when the silhouette is visible, it becomes blurred and the movement is quite jittery. I have the player ignored on the Culling Mask which I have confirmed is working, but not for the silhouette. My knowledge of the motion blur algorithm is limited, so I'm not really sure what, if anything can be done. Perhaps there is another way to achieve this silhouette effect?

I'm running an older Unity 4.3 on Windows 8 with an NVidia GTX 770 w/ Amplify Motion for Unity 4.
