Vray Animation - Problem with dark shadows

[tampac66]

[ATTACH=CONFIG]45733[/ATTACH]

When i render a still image, everything looks fine. However, when I render an animation the shadows become very dark, as if the secondary bounces aren't being taken into account or something.

 

I rendered the Light Cache for the animation first. Then rendered the IR Map. Then loaded those two and rendered the final animation.

 

Any ideas why this is happening?
