Interface
By default, both Scanline and Ray Tracing are enabled, which lets the mental
ray renderer use the two methods in combination to render the scene. Scanline
rendering is used for direct illumination (“primary rays”) only; ray tracing is
used for indirect illumination (caustics and global illumination) as well as
reflections, refractions, and lens effects.
You can disable one or the other option, but not both. For example, if only
ray tracing is enabled and you turn it off, 3ds Max enables scanline rendering.
Scanline group
Enable When on, the renderer can use scanline rendering. When off, the
renderer uses the ray-tracing method only. Scanline rendering is faster than
ray tracing, but cannot generate reflections, refractions, shadows, depth of
field, or indirect lighting. Default=on.
