FPS

How come FPS can be set so high. It is my
understanding the 18 FPS is enough to look
real. Most movies are filmed at 24 FPS.
Also are the lightmapping and bubble column
just animation?

I've written exhaustive topics about this.

24 fps IS what films use. It is hardly the fastest motion perception that humans can see. 24fps is fine for character-driven stories. I don't see football games shot at 24fps.

The difference and improvement between 24, 30, 60, and 80 is massive and I think even a casual viewer would notice the difference even if he/she could not describe exactly why faster looks better.

You can create the illusion of motion with as few as 15fps, but that does not mean it looks good or is something we should do. Try running the Aquarium at 20fps and tell me if it looks as good as 60.

You're right it does not look as good.It looks
good at about 40 FPS. What about the bubble column
and lightmapping is that an animation? Does anyone
know?

The lightplay is a texture map (bitmap) that "travels" across the coral objects.

The bubble column is a pair of texture maps that travel over slightly twisted shapes.

Plus individual bubbles that move back and forth as they rise.
