hello.
im working on a project where i need to have an infinite amount of cones [ the ones for the roads usually orange and white and pointy things]
pop out from the ground and land infront of a car.

im not too sure on how to do this. this like a 2-3 sec shot.
just pop up and land back on the ground [they will be animated with some squash stretch etc ]
-----------

so i thought about instances, i read the docs from maya, they did not tell much.
by that i mean they gave no insights on how to use them, just an explaination of what they are.

-----------------

i also tried actual geometry instancing;
but that prove too costly for render time and slow down - these are some what detailed nurbs cones, and i would need a seemingly infinite amount of them on screen at a given time [2-3 sec]

i also thought about doing it in post, but that is if it all fails from the other steps i mentioned.

if anyone have any ideas or have done similar project, please help me out.
