We've had other discussions here in the forum concerning this issue and if you're tremendously interested, I would highly suggest you go and hunt those down for more information. Short version, Eovia released their Physics plug in for Carrara 1.0 before they surrendered developing the code and Carrara went into La La land. Fortunately for all of us, Eovia snagged it and now we're here, BUT, they didn't sell Eovia the Physics plug in stuff for the version they have in the field. Consequently, you can only get the Physics plug-in into the Eovia version of C if you own the licensed flavor from Metacreations and port over the plug in. Since it's a licensed component of the code, downloading it or distributing it has been strictly forbidden so you have to really do some hunting to get a real live copy of Metacreations C (at least as far as I'm aware, I haven't heard any noise from Metacreations or Corel about turning loose this plug-in for free). Hope this answers some of your questions. -Kix
