Fire is IN Carrara... you'll have to goof with it a lot to get any specific look you're after. Tree Druid is very good, as noted elsewhere. Worth the money. For rain, use Carrara's particle system. There's even a rain pre-set. Again, you'll have to play with it a lot to get the look the way you want it. Waves can be very hard, if you're talking about photorealistic ones with foam, churn, and spray. Making gentle waves within Carrara is easy -- but curling, crashing waves will likely need to be a combination of FX composited together. At the end of this month, the movie "The Perfect Storm" will be released... soon after, several of the FX magazines will probably have articles that talk a little bit about how the ocean FX were done. I'd look into that. --
