Originally posted by raz I work in this field (I'm a 3D freelancer ), and I tell you, even with CAD models - you have to convert them into something "usable" for a animation program or re-model them almost from scratch - but that is not the main problem, the main problem is to simulate water - and to make it look good or photorealistic and that is very hard. So a few seconds of presenting this future would probably cost to much to do.
I also work in 3D and agree. It would be
way more expensive to do in 3D than to just do a quick 2d composite. Speed, quality, price... but you can only choose two.
