Hey Boris,

I'm just hazarding a guess here...

Have you checked that the camera you are rendering with has 'Auto Render Clip Plane' switched off?

If you have that option ticked on, Maya will automatically adjust your clipping plane for a 'best fit' on each frame, this will cause variation in your depth maps as your particleShape bounding box changes size as particles are emitted into it.

Switch that option 'off' and set the clipping plane values manually and see if that helps.

regards
