I know this has been requested before and the request within the TyFlow motion blur thread is similar. But I've very often getting problems with motion blur in Corona because it does not support changing topology. ANd it's very annyoing then having to turn off motion blur on everything! Also there are times, especially when working with particle that you don't want motion blur even if you want it on the rest of the scene. It would be very nice you could manually select what has or has not got motion blur instead of a ON/OFF switch for the entire scene.
