If the raytracer needs to create additional rays to determine the color of a transparent object, such as glass or clear plastic, the Transmittance bounce from 1 to 16 option allows you to specify the number of additional rays necessary.
-
We recommend setting this control is 5. Although the raytracer supports up to 16 transparent bounces for those models that contain many transparent surfaces, such as a milk bottle factory, a single object can only be hit with 5 transparent bounces.
-
Because the effect of these settings is different for each model and material in the model, you are encouraged to modify these settings and re-run the raytracing command several times to get the effects that you want.
-
Transmittance bounces are expensive in terms of performance. This safeguard prevents recursion overflow such as the inside of a Christmas tree ornament or other perfectly, spherical, shiny transparent objects.
-
Color intensity decreases with each bounce.
