Carrara has so many features I love but LIGHTS would be high on the list of my favourites. You can create some really interesting special effects such as lasers. Experiments are endless.as there are a great many attributes you can apply or animate. My wish list would be for "Realistic Ocean " although you can make some interesting looking waves with a terrain and using the special shaders from the shader room then animating the terrain with a wave modifier. The orca ocean plugin helps with floating objects. By the way "Animators " dont forget to check out CarraraTors forum Heaps of information here on animation and other stuff.
