3Delight Glass allows rendering a variety of translucent materials, going from simple coloured glass and translucent plastics down to soap bubbles with complex light interference effects. Under the hood is the production-proven GGX BRDF.

Glass can't have coloured reflection or refraction. It reflects and refracts light unaltered. Plastics on the other hand produce coloured reflections and refractions and this colour should be set to the colour of the plastic. |

This controls the specular roughness (for the GGX BRDF). The larger the value, the rougher is the surface. A roughness of zero generates mirror reflections.
IOR
The index of refraction to use to calculate Fresnel reflections. Higher values generate more prominent specular reflections. Note that there is a separate controls for refractions.
Thin Film
Enables thin-film interference. Thin film interference is a complex phenomena that depends on many variables, including viewing position and usually generates rich patterns on top of the rendered surface. 3Delight performs a physically correct light interference simulation of this phenomena.

It is impossible for real world materials to have different IOR for reflection and refraction. It is useful in a context where 3D objects are not modeled properly. A good example is a soap bubble: the walls of the bubble are so thin that they are usually modeled using a single surface. In this case the IOR for refraction has to be set to 1 to simulate such a thin medium but the reflection could be set to a value higher than 1. |

Lookdev Example: MarblesWe will try to approximate the look of this marble.
So we have a render that has many of the features of the original image. To continue the look development, one can use better lighting, internal object structure (air pockets) and varying thin-film thickness. |
