fumefx 4, motion blur

[finalightvfx]

hi Kresimir,

thanks for the scene. i tried it out and couldn't get any noticable motion blur. an a/b only showed some slight difference in the pixels with mblur on and off. this was both in max2012 and 2015. it does seem to blur the fire more than the smoke however not matching 2.0 frame duration - more like about .25-.5.
