Turrning off volume rendering interpolation

Hello,

I can’t find a way, not in the interface anyway, to turn off interpolation (i.e. selecting the nearest neighbour method) in Paraview. I see that 3D Slicer has it. Am I missing something? Some data looks better without it.
Thanks!

Looking for this as well. Is it really not possible? Want to do the equivalent of SetInterpolationTypeToNearest on the vtkVolumeProperty in VTK.
