Maya Tutorials . Fishes Effect
This tutorial is done by Autodesk Maya, using Dynamic to create Fishes animation, we also can control fishs direction too. After rendering, using Adobe After Effect to edit and come out this tutorial, this tutorials is study other website to refining the design. Don't waste time, let's start our tutorial, Thanks you!

The Final Result 完成图

Step 01
Open your Maya, at beginning We need a fish modeling, Maybe you can download to other site, now I build a fish modeling, remember that the modeling must facing like below image.

Step 02
At Animation, Select the Fish Modeling, goto Create Deformers > Nonlinear > Sine.

Step 03
Select the Sine Handle, set Rotate_X to 90, Rotate_Y to 90, Base on below image setting the Sine Handle and Inputs.

Step 04
After that Press Crtl+A, Open the Attributes, at the offset right click to Create New Expression.

Step 05
Open the Expression Editor, at Expression typing "sine1.offset=frame/30", than press Create.

Step 06
Finish Step01 to Step06, the fish animation is done. Select the fish modeling and the Sine Handle, Group it. Name it "Fish".

Step 07
Select the Fish Group, Scale it smaller as you like. After that create a Plan, rotate_Z to 90, Name it "Emit_Fish".

Step 08
Select the Emit_Fish Plan, change to Dynamics, goto Particles > Emit from Object Option.

Step 11
Goto Create > Locator, to create a locator to control the fish particles.

Step 12
Want to control, so we need to select Particles1 and Locator1, goto Particles > Goal. After this step, All the fish particles will follow to Locator.

Step 13
But all the fish will same animation to follow to Locator, so we need to add Turbulence, goto Fields > Turbulence.

Step 14
At Turbulence Attribute, edit the Magnitude to 100, Attenuation to 0.

Step 15
Select Particle1, at setting edit Conserve to 8 , Goal Smoothness to 4 , Goal Weight[0] to 0.4 .

Step 16
Is Done!! select the Locator to animation it, than will come out the fishs animation. you also ca base on particles attribute to setting how much fish you want to come out.
