Hello I am helping my friend with a promo about a fish service, I have created the top part of an ocean/sea and I am trying to make a transition underwater. Andrew Kramer from Video Copilot posted a video tutorial about submerging with pictures or animating a camera through one surface to another below but I have made an underwater scene with animation occuring, not images. How can I submerge from the top of the ocean to underwater with it looking smooth and realistic?
Do you know any tutorial? or have you seen this done before?
