Overview
The Reflections and Refractions group of attributes control the appearance of reflections and refractions of objects (also know as specular reflections).
The Reflections and Refractions group
Enable Reflections and Refractions
Specifies wether or not we want to see reflections and refractions of objects. Setting this to 'off' is equivalent to setting the Number of Bounces to '0'. The default value is 'on'.
Number Of Bounces
Sets an upper limit on how many levels of reflections/refractions we want to see (i.e. the number of bounces the ray-traced ray can travel). The default value is '2'.
