Problems with fur shader. Please help!

[cinemafan1980]

Hi all! I have a problem with the "fur output shader". I have an UV surface that have the fur shader. The object is rotating in "y" and the parameters of the shader are animated. When I render single frames troughout the animation, all works well and I can see the fur; but when I render the animation, SOFT doesn't render the output shader and I can't see any fur. What I'm doing wrong? Thanks a lot...
