You easily buy the rights to the book series from the author, Taylor Anderson. Now, you need to figure some stuff out. The first issue is nudity. Now, there are scenes of nudity within the book. One is that the natives of the new world the human characters find themselves in do not wear shirts, so the women are barebreasted. Now, the natives are also descendants of lemurs, so they're also furry. So, do you really want the CGI animators to make a bunch of furry tits? This would attract a certain audience but might also alienate some.

The second is where to film. Most of the initial part of the series takes place in Indonesia, so you could just go there and film. However, that would be expensive and dangerous, given the state of the area. Another option is to go to the Philippines, there's plenty of areas there that could be used. This would be less expensive and safer, but you'd have to deal with an unstable foreign government. The final option is the Americas. Parts of Florida and the Caribbean could be used, as well as costal areas of Mexico. This would be relatively cheap and easy, but might not come across as authentic.

The final issue is CGI. Now, there are a lot of areas where you'll have to use motion capture and CGI, he question is how much. The first is minimal, that means only the Lemurians and their enemies the Grik will be CGI, everything else will be real. This is the most expensive option, as you'll need to build a lot of sets and possibly even a ship. The second is average CGI. This means that ship battles will be CGI instead of models like the original Star Wars. It would be cheaper, but parts would look more fake. The final option is extensive CGI, where ships, cities, characters and even sets will be CGI, giving a very false appearance, but being cheapest.
