thank's a lot Jozvex, hyltom, 3dtrialpractice, Isega77, and ivox3.
actually, yesterday, before rendering, i just added a simple 5sec material for lamp, thinking i wouldn't get any SSS result anyway, and was very surprised of the result. So now i know how to get SSS -> just do it in 5sec
I'd have to render it a bit longer to have less noise, but.... well...i'm tired of this scene.... i'll close this with this little multilight animation, and then i can send the lamp and the pouf to hyltom
