The mental ray
®
renderer from mental images
®
is a general-purpose renderer that can generate
physically correct simulations of lighting effects,
including
ray-traced reflections and refractions
(page 3–87)
, caustics (page 3–91) ,and global
illuminat ion (page 3–92)
.

Same scene rendered with the mental ray renderer
The second rendering, done with the mental ray renderer,
shows caustics cast by refraction through the martini glass.
Caustics are also visible in the reflection on the cocktail
shaker.
The mental ray renderer in 3ds Max supports the
mental ray version 2 (mi2) and version 3 (mi3)
formats. It does not support the mental ray version
1(mi1)format.

Compared to the default 3ds Max scanline
renderer, the mental ray renderer relieves you of
the need to simulate complex lighting effects "by
