Instancer And Curve Flow Tutorial By Aziz Khan

Hello Friends!

In this tutorial I will show you how to use (Curve flow) with instancer to create flock of birds, insects, Fishes, sheep's, cows and etc. Maya has wide range of powerful effects to create unbelievable animations and visual effects, that is why the most film industries are prefer to work with Maya.

In this tutorial I will show you how to create flock of fish and how to control their random motion, before going to start this tutorial I assume that you should have some thing in your scene any object it dose not matter, what object is it can be fish, bird, robot, car any thing you have but I will use fish in this tutorial, when you working with (curve flow) you should have any (CV Curve) drawn in scene, like mine below. ok get ready we are going to start.

Fire up Maya if you already running just make new scene to work nice and neat.

1-First of all you should create some thing link in the image below if you have fish model do as same as me. otherwise you can just follow along  with single CV Curve to experience to do on yourself later on. I am using fish here if you have any object will serve.

2-Now make sure you are in Dynamics type if you are not just change it to Dynamics like picture below.

3-Now select the curve to use curve flow, like in image illustrated below.

4-Ok with curve selected go to (Effects>>Create Curve Flow) as in picture down.

5-Now hit play and you should see the Particles are along the path moving like image below.

6-Now select one of the circles which is created by Curve Flow and then increase the value of Scale  in Channel Box, you should scale it little bit to have realistic motion along the curve, I have scale just on of the circles if you like you can scale them in different Sizes, like the picture illustrating down.

7-Ok select the node which is in the picture below indicating.

8-Now in channel box give different values in Locaters value box, basically locaters are attached to circles if you change the values in locater box you will see the circles are moving too along the path, if you provide long distance between 2 circles when particles are there what will happen, particles will move fast till next circle, where the distance is short or near between 2 circles Particles will move very slow to next circle, change the distance between these circles and you will see what will happen. like in the picture below.

9-When you happy with distance of circles its time to Convert the particles to model in scene, ok to do this first select the model in scene which you want to flow along the curve in this case I am using fish model, as I told you before you can use any object in your scene no problem then hold down the (Shift key) then just use left mouse click. as in the picture below.

10-Now with the model and Particles selected go to (Particles>>Instancer (Replacement) hit the small rectangular box as like the image down.
