Make a scene with a box and lights and apply an SSS shader in Pre-pass based illumination map mode.
Put a unchanged vray material in the vray override global switches.
Render still calculates pre pass even though it only renders the override resulting in longer rendertime for an identical image.

I mentioned this before, I don´t remember Vlados answer though…I do a lot of medical animations with mostly SSS mats, so it´s quite annoying…

We haven’t managed to fix this one unfortunately; will try to get it done for the next SP.
There is also raytraced sss - not sure how applicable it is your case, but it doesn’t require a prepass.
Best regards,
