Rendering Fumefx "slices"

[p Hagar]

What I would like to do is basically be able to render a slice of a sim as if "Show Slice" in the FumeFX Modifier>Viewport panel actually affected the rendering and not just the viewport. Any ideas on how to do this?

I've been looking at using Krakatoa to do something like this but am having trouble getting the Krakatoa renders to look anywhere near as good as a straight Fumefx render. I'm a noob using Krakatoa so I'm sure that has something to do with it.

Any help is appreciated!
