Fishy

The fish body started off as a lofted surface, converted to polygons.



I then split and extruded faces to make the fins, tail and eye socket.



The texture reference is this fish.





I added a sine deformer and a nurbs controller.



I attatched the controls of the sine deformer to new attributes on the controller, making sure to give 'offset' an unlimited maximum value so the fish can keep swimming.




To animate, I attatched the controller to a motion path and set keys for the sine offset at the start and end, careful not to key anything else.



I'm very happy with the result, the fish movement is realistic. The rig makes animating the fish along any path a lot easier.
