Render Elements Panel and Rollout 131
Other elements do not include the scene
backg round. Include this elem ent if you want
to use the background in compositing.
The background is not trimmed against
geometry, so elemen ts should be composited
over the background. See Compositing Rendered
Elements (page 3–134) .
• Blend: A custom combination of the previous
elements.
The Blend element displays an additional Blend
Element Parameters rollout (page 3–140).
• Diff us e: The diffuse component of the
rendering.
The Diffuse element displays an additional
Diffuse Texture Element rollout (page 3–143).
• Hair and Fur: The component of the rendering
created by the Hair and Fur modifier (page
1–516).SeeHair and Fur Render Element (page
3–140).
• Illuminance HDR Data: Generates an image
containing32–bitfloating-pointdatathat
can b e used for analyzing the amount of
light that falls on a surface perpendicular to
its norma l. The i lluminance data ignores
material characteristics such as reflectance and
transmittance.
Illuminance is not related to surface properties.
For best results, render with mental ray
or another renderer that supports 32–bit
floating-point output and set the output format
to PIC, HDR, or EXR. If using the scanline
renderer or another renderer that doesn’t
support 32–bit floating-point output, set
theScaleFactorparameter,whichactsasa
multiplier , to adjust the range of values for the
output data.
• Ink: The Ink component (borders) of Ink ’n
Paint materials (page 2–1605).
• Light i ng : The effect of direct and indirect
lights and shadows in the scene.
The Lighting element displays an additional
Lighting Texture Element rollout (page 3–141).
• Lum inance HDR Data: Generates an image
containing 32–bit floating-point data that can
be used for analyzing the perceived br ig htness
of a surface after light has been “absorbed”
by the material of the surface. The luminance
data considers material characteristics such as
reflectance and transmittance.
Luninance takes surface properties into account.
For best results, render with mental ray
or another renderer that supports 32–bit
floating-point output and set the output format
to PIC, HDR, or EXR . If using the scanline
renderer or another renderer that doesn’t
support 32–bit floating-point output, set
theScaleFactorparameter,whichactsasa
multiplier , to adjust the range of values for the
output data.
• Material ID: Retains the material ID
information assigned to an object. This
information is useful when you are making
