If the raytracer needs to spawn additional reflection rays to determine the color of a reflective object, such as a mirror, the Reflective bounce from 1 to 16 option allows you to specify the number of additional rays.
-
We recommend setting this control to 2 because, in most cases, only two reflections are required to correctly determine the pixel color of a reflective surface. Because most objects in nature are not very reflective, a high setting like 16 would be necessary only if you were conducting a study in a house of mirrors.
-
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 required effects.
-
Reflective bounces are expensive in terms of performance.
-
Color intensity decreases with each bounce.
