I don't think you can with 3ds max...got a pretty damn poor exporter...
I hate 3ds max's exporter, it sucksss
I'm not sure about this since I don't have DBPro, but I think db pro is particle capable(has a command for particles), if there is, just use the built in particle system...(in DB pro)
and what about plugins(plugin for exporting or plugin for a particle effect)
note: I've had a bad time with 3ds max trying to export (everything that isn't a still object--->>no anims or anything with moving vertices)
