    Default light trails on path shutter speed + motion blur

    Couldn't find anything in the forums so am posting but if you have a link to a similar thread it would be helpful - thanks.

    I've been experimenting with shutter speed and motion blur to generate light trails from moving objects (cars). Unfortunately not got the result I was hoping for.

    Attached renders are from a test scene with vray lights linked to a moving object on a path constraint to a circle. The object goes round 10 times over 1000frames.
    I expected there to be circular trails generated but I only get straight lines - can anyone enlighten me on why? (excuse the pun)

    Thanks!

    perfect - thanks!

    edit:

    new problem - trails seem to have stuttering see attached
    also noticed the selected frame seems to render the light source without the blur, any ideas how to eliminate this?

    thanks again
