I have a calm ocean with a physical sun and sky and a custom cloud fluid in the sky, and polygonal objects parented to floating object on the ocean surface.

It takes my computer 20 minutes to render each frame of this HD animation so I'm pretty disappointed to find out after a day of rendering that the object aren't floating in the animation.

If I playback the animation in Maya, the objects float as expected. But after running the batch render, everything works(The day/night cycle I animated, the clouds, the subtle ocean waves), but my floating objects are completely still.
