Nested Dielectrics

[kosso_olli]

Is this something that V-Ray can do already or is it something that should be placed in the wishlist-section? For renderings things like beverages, this would be a huge help, the results look very convincing.

Definitely doable with Vray, as long as the bubbles have an ior of 1.

EDIT: Meant to add an test render

To me this result looks incorrect. It is missing the total internal reflection inside the bubbles. The result seems similar to the version in Arnold without Nested Dielectrics.

Hmm..ok. I'll try it again shortly. Can you pick one of those images which you think shows it best?
I was actually using the example on the second link, rather than the abstract forms, so maybe I chose wrongly

Is "reflect on back-side" turned on in the IOR-1 material of the bubbles?

I do have reflect on back side checked, so maybe it's just the particular scene that is not showing as many internal reflections as the abstract examples due to the lack of stuff to refract...
