motion blur step broken?

[japetus]

Trying to simulate some steam with the particle shader...as far as I understand the help files, decreasing the motion blur step should smooth it out a bit by copying particles, but it seems to have no effect. I'm in Point mode with motion blur forced on... tried values like .1, .5, to no change.

I'm on Max 2022 and Phoenix 4.41

Hey, can you share how it looks? Decreasing the Motion Blur Step option will eliminate spacing between the motion blurred particle streaks, but there is also another option - Motion Blur Limit, which is the maximum number of particles per streak. Could it be too low?

Well now, I started a new scene and did a quick simulation and of course the motion blur steps are functioning just as they should...

Sooo what is the difference? There are no known bugs with these options, so if you need help finding out what the issue was, send over the old scene.

Cheers!
