v5I is what we were looking at getting. The ecosystems will be particularly useful, but v4p is what they had a demo of on the website. At least that's what I found. I guess we'll have to figure out the network render as the majority of our scenes will contain water. Another question, will we need poser if we want to animate fish movements, both swimming and gills breathing? We do fishing/hunting television and our reason for wanting to go 3d is for some short illustration purposes. After doing research I've really liked what I have seen vue do with terrains and the simplicity of its us, the next step is figured out how to get fish/animals into the scenes. Like I said in the first post, no one here has any 3d experience so this is a whole new realm for us.
