radmc3d is a Monte Carlo radiative transfer code that can produce spectra and images for dust continuum and line radiation. I've written some code to save out a yt dataset into the format it uses for its AMR input files. It needs some cleaning up and documentation, but if this is something other people are interested in, I'd be happy to try to add it to yt code base. In principle, this would let any code with a yt frontend interface with radmc3d without too much hassle.
