TIP In some cases, you might want to set Max. Refractions high and Max.

Reflections low. For example, you might have the camera looking through several

glasses that are lined up, so they're overlapping from the camera's point of view.

In this situation, you might want the light rays to refract twice for each glass (once

for each layer), so you'd set Max. Refractions to 2 x [number of glasses]. However,

to save rendering time, you could set Max. Reflections to 1, resulting in accurate

multi-layer refraction with a relatively fast rendering time.

Max. Depth Limits the combination of reflection and refraction. Tracing of

a ray stops when the total number of reflections and refractions reaches the

Max Depth. For example, if Max Depth equals 3 and the two trace depths

each equal the default value of 2, a ray can be reflected twice and refracted

once, or vice versa, but it can’t be reflected and refracted four times. Default=6.

Max. Reflections Sets the number of times a ray can be reflected. At 0, no

reflection occurs. At 1, the ray can be reflected once only. At 2, the ray can

be reflected twice, and so on. Default=6.

Max. Refractions Sets the number of times a ray can be refracted. At 0, no

refraction occurs. At 1, the ray can be refracted once only. At 2, the ray can

be refracted twice, and so on. Default=6.

Translator Options rollout

Note: The Processing panel appears only when the mental ray renderer is the

currently active renderer.

Controls in this rollout affect the general operation of the mental ray renderer.

They also control the mental ray translator, which can save to an

MI file on

page 7848 . The translation is in mental ray version 3 (mi3) format. The translator

does not support mental ray version 1 (mi1).
