what do you think ?
a think that is it's a gi, it must be increased to get more rays!
try to use OA
and never forget that the colors of the objects will make the difference because it's the GI, so it's like using a color in a light! and never forget that if you mix 3 lights: Red, Green, Blue; you'll get a white!
.... à la mémoire de Kazouz
yep = it's GI
