Hi all,
inspired by Pionier testing glass and liquid materials, i did test also in my old scene of orange juice to test if i can fake good the orange juice ( since the SSS is not available yet ), but i think i'm far from it right now : it looks like a limonade lol
I used an light yellow for translucency with a 0.8 value
+ Reflection has light orange/yellow color
+refraction : falloff ( orange color + yellow light color ) + very low glossiness
+ Diffuse is 0

here is my indigo test of this scene :
-
refraction glossiness might be too low in this case, could be a little higher, and i would raise absorbtion distance too... that should get you closer to the indigo result ;)

Talking about Absorption : I've found that when i add this most little value to absorption the preview i'm getting of the material is black ! can't see wich is the right value.

Great image! I like the corona version better, only do as rawalanche says, it looks more like a pudding now ;). Also the texture is too visible on the orange slice, try using MTD, and/or reflect texture

It's dependent on the size of material preview shaderball... In compact material editor, there is a way to change shaderball size, but in slate, i don't think there is one...

Here is a 30 min update : i've used a falloff for the translucency ( orange & yellow )
I think there is no enough absorption of the light ( the light should be very close so we can see something but it burns all the other geometry ) ... it needs real sss...
I've tested the absorption value tested all values but nothing changed.
-
using translucency itself is the problem ;) i would not use it for orange juice, or perhaps just a very small fraction (maximally 0,1)
-
Here is a final try, not really satisfied with but looks good anyway, waiting for real sss...
i've found when activating DOF in corona, the fireflies appear, so i've used only depth_map in AE.
