■ emulation Performs a simpler internal calculation for light falloff within
the buffer render. It applies only to the buffer hair rendering itself, not the
3ds Max scene. This mode omits features such as illumination textures on
the hair, and light falloff calculation might be slightly inaccurate, but
rendering is somewhat faster.
Raytrace the Reflections/Refractions Available only for the “buffer” Hairs
option. When on, reflections and refractions are ray-traced. When off, they
are calculated as usual. Turning this option on can increase realism at the cost
of render time. Default=off.
Motion Blur group
In order to render motion-blurred hairs, Motion Blur must be enabled for the
growth object.
Duration The number of frames over which motion blur is calculated for
each frame.
Interval The point in the duration at which the “snapshot” of the hair is
captured, before blurring. The choices are “start”, “middle”, and “end”. The
default is “middle”, which causes blurring to occur at the start and end of the
duration.
Buffer Rendering Options group
This setting applies only to the
”buffer” rendering method on page 6388 .
Oversampling Controls the level of antialiasing applied to the Hair “buffer”
render. The available choices are “draft”, “low”, “medium”, “high”, and
“maximum”. The “draft” setting uses no antialiasing; “high” is suitable for
most final renders; in extreme cases, use “maximum”. The higher the
Oversampling level, the greater the memory requirements and render time.
Default=”low.”
Composite Method group
This option lets you choose the method by which Hair composites hair with
the rest of the scene. Compositing options are available only with the “buffer”
rendering method.
■ None Renders the hair only, with occlusion. The resulting image is ready
to composite.
■ Off Renders hair shadows but not the hair.
