RayZ

The Concept here is very simple and ordinary, Due to some sort of a disturbance or occurrence of water quakes the scared ray fish are swimming (migrating) to a new place.

Technical Creation: My Ray Fish, This file particularly is an example of Particle Crowd Multiplication and Instancers. The Rays have been rigged and animated using dynamic rigs (with the use of hair follicle) where the curve is been made dynamic therefore object behavior (simulations) can be realistic matching the underwater environments.
Another property covered in this file is the disturbance of sand when the wing of the ray fish touches the sandy floor, and sand particle simulation can be observed, Lastly the Camera Depth of field.... The fish which are far are blur.

To show the water quake sort of a disturbance in the deep blue part of this file, theres another movie file running, i hope it can be observed.

The drawbacks of this file, maybe I might hesitate to mention is the best quality (i dint that the Best pc to render), and i havnt re-edited the file with music, I just felt it wud be offensive to use soundclips that arent mine.

Hope U like this Video....
