Increase Motion Blur Effect 2.81 I'm a first time blender user who would like the increase the motion blur effect for my scene. Essentially, my goal is to reproduce this; I have followed that user's instructions(I have yet to overlay the images though). 

I would like to increase the blur trail of my molecule and emphasize the rotation. I'm open to a different approach! Thanks!



This is my shutter curve:
To exaggerate motion blur use a larger value for the shutter. The slider is limited to 1, but  click on the shutter value and manually type a larger number.



Also, don't use rolling shutter, set it to none.
