only if the mental ray renderer is the currently activerenderer.

The mental ray Arch (architectural) & Design material

improves the image quality of architectural renderingsand improves workflow and performance in general and

for glossy surfaces such as floors in particular. Special

features include self-illumination, advanced options for

reflectivity and transparency, ambient occlusion settings,and the ability to round off sharp corners and edges as a

rendering effect.

TipThe Arch & Design material supports hardware-based

viewport display for improved feedback while editing itsparameters. For more infomation, seeShow

Standard/Hardware Map in Viewport.

TipThe Arch & Design material interface has built-in

descriptions of all of its important parameters. To view atooltip describing a parameter of interest, position the

mouse cursor over the control's spinner, color swatch,

Procedures

To create a physically correct, self-illuminated surface:

An example of this application is a realistic halogen

pendant luminaire with a translucent shade, such as

frosted glass.

Create your geometry and obtain or create aphotometric file of the luminaire. Determine the

lamp color and intensity, as measured or provided

by the manufacturer; for example: 1,500 cd/m2and 3,700 degrees Kelvin. Enabletone mapping

andglobal illumination.

Create a photometric light (the halogen lamp) and set

its color and intensity.

Turn off the light source's Affect Specular property.

Create and place the light-shade geometry and apply

an Arch & Design material to it.On the Self Illumination (Glow) rollout, set the same

color and intensity you applied to the light source.

Also turn off the Illuminates The Scene (WhenUsing FG) check box in the Glow Options group.

Render the scene.

NoteBecause the material is energy conserving, theactual diffuse level used depends on the reflectivity

and transparency, as discussed in the introductory

section, above.

Color

Controls thediffuse color.The diffuse color is the

color in direct light. Default=50% gray.

Roughness

Roughnesscontrols how quickly the diffusecomponent blends into the ambient component.

Range=0.0 to 1.0. Default=0.0.

The diffuse component uses the Oren-Nayar shading

model. When the Roughness value is 0.0 this is

identical to classical Lambertian shading, but withhigher values the surface gets a more powdery look,

as shown in the following illustration.

The Reflectivity and Color values combine to definethe level of reflections as well as the intensity of the

traditional highlight, also known as the specular

highlight.

This value is the maximum value; the actual valuealso depends on the angle of the surface and comes

from the BRDF curve. This curve (seeBRDF rollout)

lets you define 0degree reflectivity for surfacesfacing the view and 90degree reflectivity for surfaces

perpendicular to the view.

NoteIn the preceding illustration, the high

Esquerda: Glossiness = 1.0; Center, 0,5; direito, 0,25

Glossy Samples

Defines the maximum number of samples (rays)

that mental ray shoots to create glossy reflections.Higher values cause slow rendering but create a

smoother result. Lower values render faster but

create a grainier result. Generally 32 is enough formost cases.

Available only when Glossiness does not equal 1.0.

Because a Glossiness value of 1.0 creates a perfect

mirror, it is meaningless to shoot multiple rays forthis case, hence only one reflection ray is shot.

NoteIf you set Glossy Samples to 0, the reflectionstake the form of a perfect mirror and only one ray

is shot, regardless of the actual value of Glossiness .You can use this to boost performance for surfaces

with very weak reflections. The highlight still

respects the Glossiness value.

Glossy reflections need to trace multiple rays toyield a smooth result, which can affect

performance. For this reason, the material includes

the following two special features designed to

enhance performance:

Amostras brilhante

Define o nmero mximo de amostras (raios) quedispara raios mentais para criar reflexos com

brilho. Valores maiselevados causam renderizao lenta, mas criar umresultado mais suave. Valores mais baixos tornar marpido, mas criar umgranulada resultado.

Fast (interpolate)

When on, a smoothing algorithm allows rays to be

reused and smoothed. The result is faster and

smoother glossy reflections at the expense ofaccuracy. Interpolation is explained in greater detail

in the section on theFast Glossy Interpolation

rollout.

NoteThis method works best on flat surfaces.

Highlights+FG only

When on, mental ray traces no actual reflection

rays. Instead, only the highlights are shown, as well

as soft reflections emulated with the help of using

Final Gathering.

The Highlights+FG Only mode takes no additionalrendering time compared to a non-glossy (diffuse)

surface, yet can yield surprisingly convincing

results. While it might not be completelyconvincing for hero objects in a scene, it can work

very well for less-essential scene elements. It tends

to work best on materials with weak reflections orextremely glossy (blurred) reflections, as shown in

the following illustration:

When off, the Reflection Color parameterdefines the color, and the Reflectivity

parameter together with the BRDF settings

defines the intensity and colors ofreflections.

When on, the Diffuse Color parameter defines thecolor of reflections, and Reflectivity parameter sets

the weight between diffuse reflections and glossy(metallic) reflections.

smoother glossy refraction at the expense ofaccuracy. Interpolation is explained in greater detail

in the section on theFast Glossy Interpolation

rollout.

NoteThis method works best on flat surfaces.

Glossy Samples

Defines the maximum number of samples (rays)

that mental ray shoots to create glossy refraction.

Higher values cause slow rendering but create asmoother result. Lower values render faster but

create a grainier result, like frosted glass. Generally

32 is enough for most cases.

Available only when Glossiness does not equal 1.0.Because a Glossiness value of 1.0 creates a

perfectly clear (non-blurry) transparency, it is

meaningless to shoot multiple rays for this case,

hence only one refraction ray is shot.

NoteIf you set Glossy Samples to 0, the refraction

takes the form of a perfect lens and only one ray is

shot, regardless of the actual value of Glossiness.You can use this to boost performance for draft

renderings.

IOR

The Index of Refraction, which is a measurement ofhow much a ray of light bends when entering amaterial.

The direction in which light bends depends on

whether it is entering or exiting the object. The Arch

& Design material use the direction of the surfacenormal as the primary cue for figuring out whether

it is entering or exiting. It is therefore important to

model transparent, refractive objects with the

surface normals pointing in the proper direction.

The IOR can also be used to define the BRDF curve,

which is what happens in the class of transparent

materials known as dielectric materials, and is

illustrated here:

Nota Este mtodo funciona melhor em superfciesplanas.

Left: IOR=1.0; Center: 1.2; Right: 1.5

Esquerda: IOR = 1,0; Center: 1,2; Direita: 1,5

The leftmost cup looks completely unrealistic and isalmost invisible. Because an IOR of 1.0, which

equals that of air, is impossible in solid matter, we

get no change in reflectivity across the material and

hence perceive no edges or changes of any kind. Onthe other hand, the center and rightmost cups have

realistic changes in reflectivity guided by the IOR.

Instead of basing the reflectivity on the IOR, you

can instead use the BRDF mode to set it manually:

A taa mais esquerda parececompletamente irrealista e quase invisvel. Porqueuma IOR de 1,0, o que equivale a do ar, impossveem matria slida, que no temos nenhum mudana refletividade em todo o material e, portanto, percebesem bordas ou alteraes de qualquer tipo.

center cup has a manually defined curve, which hasbeen set to a 90 degree reflectivity of 1.0 and a 0

degree reflectivity of 0.2; this looks a bit more like

metallized glass. The rightmost cup uses the same

BRDF curve, but instead is set tothin-walledtransparency.Clearly, this method is better for

making non-refractive objects than simply setting

IOR to 1.0, as we tried above.

Translucency group

Translucency is handled as a special case of

transparency; in order to use translucency there must

first exist some level of transparency. Theimplementation of translucency in the Arch & Design

material is a simplification concerned solely with the

transport of light from the back of an object to its front

faces and is not true SSS (subsurface scattering) effect.You can create an SSS-like effect by using glossytransparency coupled with translucency, but this is

neither as fast nor as powerful as the dedicatedSSSshaders.

Translucency

When on, the remaining Translucency become

available and take effect when rendering.

Weight

Determines how much of the existing transparency

is used as translucency. For example, if

Weight=0.0, all of the transparency is used astransparency. If Weight=0.3, 30 percent of the

transparency is used as translucency.

Translucency is intended for use primarily inthin-walled mode,as in the example above) to

At 1.0, the highlight is round; that is, no anisotropy.At 0.01, the highlight is elongated. One axis of the

highlight graph changes to show changes in this

parameter. Default=1.0.

TipWhen using texture-mapped Anisotropy Rotation,make sure the texture is not antialiased (filtered). You

can achieve this by setting the map's Blur parameter to

0.0. Otherwise the antialiased pixels cause local

vortices in the anisotropy that appear as seam artifacts.

Automatic/Map Channel

Lets you optionally apply anisotropy to a specific map

channel.

If the Map Channel setting is Automatic, the base

rotation follows the object's local coordinate system.

If it is any other value (in other words, a specific mapchannel), the space that defines the stretch directions

of the highlights is derived from that channel's texturespace.

WarningDeriving the anisotropy from the texture

space creates only one space per triangle and can

cause visible seams between triangles.

BRDF stands for bidirectional reflectance distributionfunction. As explained in theintroduction,this property

lets the material's reflectivity be ultimately guided by the

angle from which the object surface is viewed.

solely by the material's index of refraction.

This is known as Fresnel reflections andfollows the behavior of most dielectric

materials such as water and glass.

This mode is used for most hybrid materials or formetals. Most materials exhibit strong reflections at

grazing angles; hence the 90 degree reflectivity

parameter can generally be kept at 1.0, using the

Reflectivity parameter to guide the overall reflectivityinstead. Metals tend to be fairly uniformly reflective

and the 0 degree reflectivity value is high (0.81.0),

but many other layered materials, such as linoleumand lacquered wood have lower 0 degree reflectivity

values, in the range 0.10.3). For further information,seeQuick Guide to Some Common Materials.

Ambient occlusion helps emulate the look of global

illumination by creating darker areas where light doesntreach without actually generating shadows. With the Arch

a per-material basis.

Shadow Color

When Use Color From Other Materials (see

shadows. It is used as the multiplier value for

completely occluded surfaces. In practice, a black

color makes the AO effect very dark; a middle-graycolor makes the effect less noticeable (brighter), and

so on.

When Use Color From Other Materials is on, thissetting determines the ratio between the standard AO

functionality with Shadow Color set to black and the

color bleeding from other materials. For example, atthe default setting, RGB=0.2, 20 percent of the AO

shadow color is derived from black and 80 percent is

derived from the color of the nearby material. If you

set Shadow Color to RGB=0.0 (black), then 100

AO, or use the global color specified on theEnvironment panel> Common Parameters rollout.

This parameter is used for doing more traditional

AO; that is, supplying an imagined ever-present

ambient light that is then attenuated by the AOeffect to create shadows.

While traditional AO is generally used when

rendering without other indirect light, you can also

combine it with existing indirect light. Bear in mindthat this ever-present ambient light is inherently

non-physical, but can possibly help lighten some

troublesome dark corners.

Round Corners group

This effect rounds off corners and straight edges as a

rendering effect only; it has no effect on geometry.

The rounding effect happens to convex corners and

surfaces that actually intersect. Concave corners that

merely touch will not display the effect. To get the effectto work in concave corners the objects must be pushed

into each other a little. The effect is intended for straight

edges and is not guaranteed to work properly for highlycurved, complex intersections.

Round Corners

When on, rounds off corners and straight edges at

render time.

Fillet Radius

Specifies the radius of the filleted corners and/or

edges.

Blend With Other Materials

By default, the rounding effect happens onlybetween surfaces of the same material, but if you

turn this on the filleting is performed against any

material.

In the following image, the molten chocolate isrounded off against the submerged objects even

though they use different materials. In actuality, the

molten chocolate is a completely flat plane.

Visible area lights cause no Highlights

When on, mental ray area lights (OmniandSpotlight)with the Show Icon In Renderer property

on create no specular highlights. Default=on.

The Show Icon In Renderer check box is found on

the light's Area Light Parameters rollout. When on,the light is visible and reflects in any glossy,

reflective objects. If both the reflection of the visible

area light and the highlight is rendered, the light is

added twice, causing an unrealistic brighteningeffect. When on, this switch causes visible area

lights to lose their highlights and instead only appear

as reflections. Note that this does not apply to the

Highlights+FG Onlymode, which doesnt actuallyreflect anything.

Skip reflections on inside (except total internal

reflection)

Most reflections inside transparent objects are veryfaint, except in the special case that occurs at certain

angles known as total internal reflection (TIR).When on, this option saves rendering time byignoring the weak reflections completely but

retaining the TIRs. Default=on.

Relative Intensity of Highlights

intensity of true reflections. When the value is 1.0,the two intensities are equal. A lower value subdues

the intensity of highlights compared to reflections,while a higher value intensifies the highlights.

When Caustics are enabled, transparent objects:

When not rendering caustics, the Arch & Designmaterial uses a shadow shader to create transparent

shadows. For objects such as window panes this is

perfectly adequate, and actually creates a betterresult than using caustics, because the direct light is

allowed to pass more or less undisturbed through

the glass into a space such as a room.Traditionally, enabling caustics in mental ray

causes all materials to stop casting transparentshadows and instead start to generate refractive

caustics. In most architectural scenes this is

undesirable; you might want a glass decoration on atable to generate caustic effect, but still want the

windows to the room to let in normal direct light.

This switch makes this possible at the materiallevel.

Quando Caustics esto habilitados, objetostransparentes:

Quando no prestao custicos, o material Arch &Design utiliza um shader sombra para criar sombrastransparentes. Para objetos como vidros isto perfeitamente adequado e realmente cria um resultadmelhor do que usar custicos, porque a luz direta permitido passar mais ou menos intacta atravs dovidro em um espao como uma sala.

because it blends neighbors of this low-resolution grid,it can cause oversmoothing. For this reason it is useful

The default is 2, and higher values will smearthe glossiness more, but are hence prone to more

oversmoothing artifacts.

In the following illustration, the reflection of the

left cup in the floor does not use interpolation,and some grain is evident (here intentionally

exaggerated). The floor tiles under the other two

cups use a half-resolution interpolation with

point lookup set to 2 (center) and 4 (right),respectively.

Esquerda: sem interpolao; Center: Olhando para cima de dois pontos; Direita:Olhando para quatro pontos.

The preceding image also illustrates one of theconsequences of using interpolation: The foot of the

left cup, which is near the floor, is reflected quitesharply, and only the parts of the cup far from the

floor are blurry. However, the interpolated

reflections of the right cups have a base level ofblurriness, due to the smoothing of interpolation,

which makes even the closest parts somewhat

blurry. In most scenes with weak glossy reflections

this discrepancy will never be noticed, but in othercases this can make things like legs of tables and

chairs feel unconnected with a glossy floor, if the

reflectivity is high. To resolve this, you can use the

High Detail Distance setting (see following).

High detail distance

This also allows an interesting trick: Set Reflection> Glossy Samples to 0, which renders reflections asif they were mirror-perfect, but also use

interpolation to introduce blur into this reflection,

and perhaps use High Detail Distance to make

nearby parts less blurry. This is a fast way to obtaina glossy reflection.

The floor tiles in the following illustration are

rendered with mirror reflections, and the blurriness

comes solely from the interpolation. This renders asfast as or faster than pure mirror reflections, yet

gives a satisfying illusion of true glossy reflections,

especially when utilizing the High Detail Distance

option, as on the right.

Single Sample from Environment

Creating realistically blurry glossy reflectionsnormally requires taking multiple samples from the

environment, which can result in grainy,

slow-rendering environment reflections. With thischeck box on, mental ray instead takes only one

sample, thus preventing the grain. This also

Lets you apply bump, displacement, and other maps. Eachleft-justified setting has a check box for enabling and

disabling the map, and a button for defining the map.

Bump

Lets you apply a bump map and multiplier.

Do not apply bumps to the diffuse shading

When off, the bumps apply to all shading components:

diffuse, highlights, reflections, refractions, etc. When

on, bumps are applied to all components except thediffuse. This means bumps are seen in reflections,

highlights, etc. but the diffuse shading shows no

bumps. It is as if the material's diffuse surface issmooth, but is covered by a bumpy lacquer coating.

Permite aplicar bump, deslocamento e outrosmapas. Cada configurao justificado esquerda temuma caixa de seleo para ativar e desativar o mapa, eum boto para definir o mapa.

coliso

Permite aplicar um mapa de relevo e multiplicador.

No se aplicam aos solavancos o sombreamento difus

Quando desligado, a solavancos aplicam a todosos componentes de sombreamento: difusa,destaques, reflexes, refraes, etc Quando ligado, ascolises so aplicados a todos os componentes, exceta difusa. Este solavancos meios so vistosem reflexes, destaques, etc, mas osombreamento difuso no mostra solavancos. como se a superfcie difusa do material bom, mas escoberta por um revestimento de laca acidentado.
