i like Cedrone Photo for me now he's a reference for art of photography and stile mood. i wanted try this simple setup lighting, and in the same scene testing a sss setup of milk,
this is my first fast attempt for set up light and milk, other materials are only placed in the scene without any correction, they need more work.
ceiling material its wrong.
if you have any advice, you are welcome :)

Doesn't look much like milk. Unless it's what Cartman drank in South Park episode, where he accidentally put Kenny's ashes into milking thinking it was cocoa :)
-
hahaha :) i remember that episode, i will search more references..but it's hard to find milk on backlight setup

Your photo references of milk show very thin layers of it, this probably misguided you. I think milk is less translucent.
-
mm, you are right.
i'm trying this setup now.
-
in absorption color i use this rgb
-
Honestly these settings are confusing for me. From what I learned absorption colour's value also affects absorption's distance. So setting darker colour is the same as setting lower distance value. Am I right? And darker "scattering" colour will make the object look more dense and lighter will make it look more transparent?

this is a definition in corona help..
absorption is controlled by setting the color that original white ray will have after traveling specific distance in the medium.
in my test the color i sselect in this parameter generate different sss color
-
if increase distance parameter you can see the color i used in abs
-
last milk set up
in the second render i used same milk setup but on direct light.
-
That looks a bit better :)
-
Looks too dark to me.

Looks too dark to me.
in both image or only the first?
-
That looks a bit better :)
all colors are near to pure white (255 255 255), with a little part of yellow, maybe it's a illumination/contrast problem
-
First option looks the best to me. This last one looks like watered milk. Not sure if you've ever seen watered milk, but that is exactly how it looks :)

It's milk, unless lit from all sides it will be dark, like in the first renders.

Yes Blank you are right, i decreased distance parameter on abs, for do milk more "dense"
this is my last setup.
-
last milk setup
-
last render in hi res.
-

Only firs looked wierd, but the last render looks just like the milk) prefious versions looked more like milk mixed up with water.
-
thank you :)
then the last one is right for you?
-
Last Version
C&C are welcome :)
-
thank you :)
then the last one is right for you?
Yes last one looks great )
-
what corona version are you using?
im with a7.1 and there is no absorption option :s
-
thank you Nekrobul
@ juanon: i'm using a daily build.
-
yes really believable milk shader good job!
-
last render in hi res.
A very good test, although the light for this case is quite controversial )

I like to add:
"Appearance
Both the fat globules and the smaller casein micelles, which are just large enough to deflect light, contribute to the opaque white color of milk. The fat globules contain some yellow-orange carotene, enough in some breeds (such as Guernsey and Jersey cattle) to impart a golden or "creamy" hue to a glass of milk. The riboflavin in the whey portion of milk has a greenish color, which sometimes can be discerned in skimmed milk or whey products.[13] Fat-free skimmed milk has only the casein micelles to scatter light, and they tend to scatter shorter-wavelength blue light more than they do red, giving skimmed milk a bluish tint.[71]"
