Luis Miguel Mora takes a look at how to get BIN files from MTC files for mist and splash simulations in RealFlow. If your intention is to render simulations with FumeFX or Krakatoa, the MTC files will not work, however you are able to generate BIN files with a little scripting.
There is a workaround by using scripting but we need to do the splash simulation twice
The key is to render the simulation twice, one simulation for mist, and another for splash. Luis notes that because a mist particle is born on the death of a splash particle, simulating both splash and mist at the same time will provide a way to display the surviving particles.
