HI - I'm rendering a flip fluid cache, with the “v” output correctly. I am seeing some MB, but I'd like to crank it up. In Maya there are options for shutter open/shutter close, etc.

Is there an easy way for me to gain up that “v” velocity vector before it gets used for MB? Is there a better approach?

I know I can do “v*1.4” or whatever when I'm writing out the sim, but I'd rather not re-sim every time I want to noodle the MB.

thanks.

For motion blur control.

The camera has a sampling tab. There you will find a Shutter Time parameter.
Here is a couple of renders. Once with no shutter time, one with a shutter time of 1, and one with a shutter time of 1 with a pixel sampling value in the render node of 12x12.

For altering the global mblur parameters, the sample tab of a cam is the way to go, as ragupasta described.

But, why do you need a re-sim? You could just insert a point sop at any time after the sim and multiply v as you described. And plus: if you like, you can even control v for each object seperately.
