Flickering In Render(maya Software)

[cpo29]

I am rendering with maya software(raytrace) and as the camera pulls back from the shot. Any geometry that is close to each other has sorting issues. Im guessing...
Anyways, these pieces of geometry are flicking back and forth in the render. Is there a value I can crank up to stop this?

Please help...

This could be a couple of things but you could try upping the sampling rate.. but my gut feeling is that you perhaps have a world size that is very large.

that is correct, the world size is large. It was created so the camera could move around in the scene, with a player perspective. At first it was intended for just a real time playblast, but I was having the same problem with that, but way worse.

Maybe I should try scaling it down? I'm worried that will affect the camera animation.

as long as the camera is grouped with everything else it will scale fine

here are 2 frames to better describe what i am talking about. the grass is on a card with an alpha, that sits above the ground geo.
