does anyone know where to get this and how to install it?I believe there is a separate installer for that option, you have to find it and run it.
OK... looking at the demo it seems like it should have installed a plugin, but didn't.
However I do remember an old thread where someone had this same question, and that person posted a link to a Mac plugin download.

It seems to still work.
