In 3ds Max, a special shadow generator type, mental ray Shadow Map, is provided
to support the mental ray renderer. If shadows are enabled (on the
Shadows
& Displacement rollout
on page 6114 of the Render Scene dialog) but shadow
maps are not enabled, then shadows for all lights are generated using the
mental ray ray-tracing algorithm. If shadow maps are enabled, then shadow
generation is based on each light’s choice of shadow generator:
■ mental ray Shadow Map Shadows are generated using the mental ray
shadow-map algorithm.
■ Shadow Map Settings on the Shadow Parameters rollout are translated
into a mental ray equivalent before shadows are generated. The quality of
shadows generated this way might not always meet expectations.
■ Area Shadows, Advanced Ray Traced Shadows, or Ray Traced
Shadows Shadows are generated using the mental ray ray-tracing
algorithm.
Motion Blur with the mental ray Renderer
Motion blur is a way to enhance the realism of a rendered animation by
simulating the way a real-world camera works. A camera has a shutter speed,
and if significant movement occurs during the time the shutter is open, the
image on film is blurred.
