Animating actual Phoenix grid with static VDB motion blur

[cb LLC]

Hi we created a static VDB basically object made out of smoke. We are planning to animate actual phoenix grid or octane proxy volume so it looks like it is flying. unfortunately there is no motion blur. I guess you cannot have MB for one VDB that is animated like a mesh? Or can you?

There are two types of moblur - when the grid moves, you don't need any special prerequisites in the cache and you should get motion blur, but for the movement of the fluid inside the container you must have a velocity channel in the cache.

Thank you. I guess grid mb only work with vray. I tried with octane and there is no mb at all.
