How can I add motion blur in a twilight rendering ?

[derei]

Is there a way to render motion blur using twilight render? I have a notebook falling from a desk and I want to "catch" it moving on air. I was wondering if twilight render can do that, or my only choice is post-production?
Also, I never did something like that, so if you have some suggestions about how this can be done (postpro) in the best manner, please tell me.
Thanks.

TWR doesn't have build-in motion blur, so you'll need to make this in post pro...
