Krakatoa Particles playback in Max viewport

This is a first test of getting a Houdini Flip Fluids sim into Max for rendering in V-Ray.

I used the Krakatoa PRT Rop driver available from this site:

Which is pretty awesome. Drivers are available for Houdini 13 and 14. The version I tested was for 14.0335. The driver is easy to install, and is then available under a custom section of the Output drivers.

As well as baking out the particles to PRT files, the Rop driver can also write out the particle velocities, which are read by Frost back in Max. V-Ray is able to use the velocity data for in-camera montionblur.
