Hi
I have meshed my particle sim using particlefluidsurface SOP but now when i render i dont get motion blur i guess it because the topology of mesh changes in every frame

Is there any work arounf for this…

thanks

Arjun

Hi,

In your particlefluidsurface sop, attribute tab, specify “v” to sample the velocity attributes from your particles.
You can also enable the “filter attributes” on the filtering tab.
Should be fine after that.

well i already have both velocity and filter enabled still it renders without motion-blur

On your Mantra node, turn on the Allow Motion Blur checkbox on the Sampling sub-tab of the Properties tab.

Did you try “Geometry velocity blur” in geometry-render-sampling tab?
