Thank you for kind words. You can try realfow by downloading the demo from here: http://www.realflow.com/n_try.php If you're into FX I would recommend trying it because it's very powerful and at the same time not very hard to use once you get familiar with the interface.
Thanks. I used madcar plugin to animate the buggy. It's a very powerful plugin driven by reactor. When you set everything up you can basically drive your vehicle around in real time on the surface of your choice. You can read more about the plugin at this tread: http://forums.cgsociety.org/showthread. ... 3&t=571932
