Hello,

Probably you have Motion Blur enabled in the settings of your renderer, but Phoenix FD has missing Velocity channel and renders with motion blur only in the Backup frames. Make sure that you have the Velocity channel exported in your Output rollout.

The other thing that could cause that is the Mesh smoothing option "Us Liquid Particles". Make sure to check our FAQ section here - https://docs.chaosgroup.com/display/...Phoenix+FD+FAQ

I would recommend getting a latest nightly build as well - as they contain quite a lot of fixes and improvements. You can find more about it here - https://forums.chaosgroup.com/forum/...nightly-builds

Hi. Georgi Zhekov thank you very much. I export Velocity channel the setting like photo1 but it still have the same problem. So I made the setting like photo 2 "Output Particles-->☑Export ☑Velocity" then the problem is solved. Is it the rignt way to solve?

Hey,

Yes - using the second method will export the velocity channel for both the particles and the grid.
