Instancer And Curve Flow Tutorial By Aziz Khan
11-Now in (Particle Instancer Option) change the (AimDirection) to (Velocity) and then hit create, as in the image below.
12-Now you should see something similar like mine here, if you notice one thing the quantity of fishes too much and their overlapping each other like the picture below, how to solve the problem? ok undo Instancer and to return to the pervious status. you think that what the hell is this I am doing? its because to enhance your practice don worry keep going on.
13-Ok when you done with undo, select that Node which we have selected in the Figure 7, and then change the values in channel box, as like the picture below,
14-If you see now we have less particles like the picture below.
15-With doing these all we still need some tweaking around the particles, ok select the Particles and then go to channel box then change these settings as in the Image down.
16-Now you are pretty done you are ready now to use (Instancer (Replacement) ok now do the same which you did in figure 9, and now you should see less fishes and with nice random motion along the path, like the image indicating below.
17-Vaila we are done now, and we need to hide our original model from scene, to do this first select your orignal model and then go to (Display>>Hide>>Hide Selection) and the model has hided, like the picture below.
And now you can play the animation and you are watching that objects are instancing very nicely along the path, you can use this technique to create Missiles, flock of birds, sheep's, butterflies, cows, fishes, and many more.
My final result is here below which I add a camera and took this final image.
