Ray-Traced Reflections and Refractions with the
mental ray Renderer
The mental ray renderer can generate reflections and refractions by ray tracing.
Ray tracing traces the path of rays sampled from the light source. Reflections
and refractions generated this way are physically accurate.
Ray-traced reflections and Refractions
To reduce the time required to generate reflections and shadows, rays are
limited by trace depth. Trace depth limits the number of times a ray can be
reflected, refracted, or both.
You can turn off ray tracing. In this case, the mental ray renderer uses scanline
rendering only. Turning off ray tracing makes the controls for all the effects
that are specific to mental ray unavailable in the Renderer's rollouts.
Ray tracing uses one of two
ray-trace acceleration methods on page 7905 .
You enable ray tracing and set trace depth in the Render Scene dialog >
Renderer panel > Rendering Algorithms rollout on page 6118 .
