I am starting work on a new project ( for fun) to recreate the crash landing from the film Memphis Belle. Whist playing around with some concepts i discovered something interesting about vector motion blur and propellers. If i add VMB the blur is OK but i tend to see the props rotating, i have in the past used a spherical alpha gradient on the props to just show the tips which get blurred. Then i found that if i make the props totally transparent they still motion blur, quite well in fact. Maybe it has something to do with internal reflection ?
It still needs more work off course, perhaps move the props back and increse the samples?

Any way here is a test render to show you what i mean. Now this was just a sound/video timing test so the textures are off, the lighting effects and colour are all just for testing. I will get around to all that once i have the whole vid animated and timed as i want

Trying to get hand animate the crash landing is tricky but i am having some joy using modynamics and a proxy object, a lot of issues can be fudged away with motion blir. smoke and debris
