When ray tracing is turned off, no reflection or refraction occurs.
The following example shows the same model with ray tracing turned off.
Trace depth controls the number of times a light ray can be reflected or
refracted. Increasing these values can increase the complexity and realism of
a rendered image, at a cost of greater rendering time.
The following example shows how increasing the trace depth improves the
rendering. Max Depth = 4; Max Reflections and Refractions = 2.
