Hi Sven,<br><br>I might be wrong, but I believe the reason it normally isn't done this way is something like this.<br><br>Let's suppose we're going to do 4 renders per frame. Then Frame 1 might use T = 0.5 , 0.75
, 1.0 , 1.25 , and Frame 2 might use T = 1.5 , 1.75 , 2.0 , 2.25.<br><br>As you can see, there's no overlap in the time domain between the two frames. If there were, the blurs would likely appear to "stutter" a bit, which could be a neat effect if it's what you want, but probably would look poor.
<br><br>One thing I experimented with a while back was turning motion blur off, changing my animation to produce slow motion (say 10x number of frames), render it across my farm, then "speed it up" using ImageMagick to average each set of 10 frames together. The results were pretty cool, because the renders were quick due to lack of Blender-provided motion blur, but still blurry thanks to rendering 10x the number of frames. If I recall, this was the only way I could actually get motion blur with fluids, but I could be mistaken. It's been a long time since I tried it.
