Render Warps
FumeFX supports various Maya Deformations at render time to bend, twist and deform FumeFX voxels after the simulation is done. Render Warps parameters control how those warps are applied.
Apply Deformations to FumeFX like you would do for other geometry in Maya. However, you will need to use the Post Processing and bake Render Warps before rendering FumeFX.
