Explode modifier and motion blur (not working).. any ideas?

Hi guys
it appears that motion blur isn’t working in cycles (both with “built in” and via the compositor) when using explode modifier on top of a particle system…
is it a known problem or am I missing something?

A.

My first guess would be that motion blur isn’t supported by cycles. If that isn’t the problem, then I would suggest changing the objects used for your particle system. If that doesn’t do it, make sure you are rendering with your CPU because I heard somewhere that Motion Blur is only available for CPU rendering. Hope I helped!
