Unhappy sss mental ray problem

Heres the thing i am making an animation of some roses using the misss_fast_skin shader, everything looks beautiful but when I batch render the roses get much brighter at a few specific frames, its always the same frames even with different cameras and from different places.

Has this happened to anyone before?? and if so, is there a workaround? please i need to make a delivery soon!!

I am using maya 2013.

Thanks in advance.

Could you elaborate what you are using to render your scene? Mental ray? Could you post a snapshot of the image and let us see what is gong on.

from one frame to another and in varying frames, not many but they are there, always the same frames.

Are you using FG or GI?

Using final gather, i got 1 directional light with depthmap shadows and 2 area lights with raytrace shadows.

Have you tried the directional light with ray traced shadows (no depth map shadows)? I have had issues in the past with sss and depth map shadows and dark splotches on skin.

Well, because I had a deadline, I resolved the issue by going back to maya 2011 (since I don't have 2012) that basically did it, why? beats me! thanks though.
