Lee Griggs walks through how he created a scene of bubbles that use nested dielectrics.
The latest version of Arnold Render offers a physically accurate way to render the boundaries between two reflective and refractive materials. The classic rendering example is ea glass, the liquid inside the glass and ice cubes. Before nested dielectrics, you had to carefully separate touching objects and work out the refractive values for things like the inside and outside of the glass. Now with the latest version of Arnold, you can set dielectric priority.
