im having problems rendering a character with the misss fast skin material, in a scene that has the Physical sky and sun set up.

All the objects looks fine, its just the body of the character, like the sss skin is not getting ilumination from the sun, or something like that, the skin is all blue, and the sss effects its like missing.

Can someone explain to me what im missing? plz HELP!

yes is set correctly.
Its a character I model sometime ago, and the sss works fine on my character.
Its the misss fast skin conected to the mix20layer.
You can see my character in these links with a FG dome and some spotlights, and you would see it looks fine, no problem with the sss set up.

I'm guessing that FG is turned on.

Mental Ray seems to have a problem with the skin SSS when using either image based, or physical sun environments.

If you want shadows and proper SSS, create a light in combination with the sky.

Imagination is more important than knowledge.
