Hello:

(*) Create an explosion with PhoenixFD with Velocity Output ON (by default is OFF).
(*) Export the simulation as .vdb format.
(*) Import the .vdb files in 3ds Max with CVolumeGrid.
(*) Set Speed multiplier= 0.5.
(*) Set Mode=Velocity based.
(*) Set Velocity=Velocity.
(*) Multiplier = as you want.
(*) Turn on Mblur  (Geometry) in the CoronaCamera.
(*) Render the animation (it's enought a few frame)

The interpolated frames (frame 1, frame 3, frame 5 etc...) are really weird.
If you use Mode=Simple, everything is ok

Is it a bug?

Further note from Francesco:

Also, if you look at my .mov file, try to see the frame 01. When the Mode: Simple, the interpolation isn't so good. There is a "violet" halo around the explosion. This "halo" doesn't exist in the frame 0 and in the frame 2.
