$phong

Pendiente: Arreglar plantilla para corregir el texto en esta página.

$phong es un parámetro de un shader(en) disponible en todos los juegos de Source desde(en) Source 2006.

Sombreado phong en la piel, el pelo y los labios de Alyx.

También está disponible en sombreado LightmappedGeneric y WorldVertexTransition en todos los juegos desde Counter-Strike: Global Offensive. proporcionando reflexión difusa a baja intensidad y resaltado especular, enmascarados con una textura que controla su intensidad mediante téxeles. Para una explicación completa, véase materiales phong(en).

Nota:El sombreado phong LightmappedGeneric y WorldVertexTransition solo está disponible en

CS:GO rama de motor. Es necesario que la luz solar ilumine el material de una entidad env_cascade_light para que funcione adecuadamente y usa sombras dinámicas generadas como máscara sobre las máscaras de sombreado tradicional ((en todos juegos desde

) env_projectedtexture 4 también afecta a los sólidos con sombreado phong activado)

Nota:El sombreado phong para LightmappedGeneric también está disponible en

Mapbase, pero se implementa distinto.

Sintaxis

Insurgency.

Pendiente: Otros juegos que no necesitan parámetros phong (como Portal 2 en adelante)

Enmascarado

Aviso:There are some caveats regarding $normalmapalphaenvmapmask and $selfillumfresnel when using $phong!

Using $selfillumfresnel without $normalmapalphaenvmapmask will mask the $envmap using the $basetexture's alpha channel.
Using $selfillumfresnel with $normalmapalphaenvmapmask will multiply the $envmap by 0.0f. Effectively disabling the effect!
When not using $selfillumfresnel. The mask used for $envmap will be the $basetexture's alpha channel unless $normalmapalphaenvmapmask is also used.
If $normalmapalphaenvmapmask is used, the $bumpmap's alpha channel will be used for Phong masking. Using either $basemapalphaphongmask or $basemapluminancephongmask will override it.

$bumpmap(en) <texture(en)>

Phong requires mask. The alpha channel(en) of a bump map(en) acts as a Phong mask by default.

$basemapalphaphongmask(en) <boolean(en)> (en todos juegos desde

)

Shader(s): VertexLitGeneric

Use $basetexture's alpha channel(en) as the Phong mask instead of $bumpmap's alpha channel(en).

Aviso:Using this with $normalmapalphaenvmapmask will override the mask used for $envmap to be the contents of the $basetexture's alpha channel!

Aviso:

Garry's Mod Using this with $normalmapalphaenvmapmask and $envmap renders in $envmap and $phong be masked by both $basemapalphaphongmask alpha channel and $normalmapalphaenvmapmask alpha channel.

$basemapluminancephongmask(en) <boolean(en)> (en todos juegos desde

)

Shader(s): VertexLitGeneric

Mask phong intensity based on the brightness of the $basetexture.

Error:Basetexture Luminance will replace the mask used for $envmap, if $normalmapalphaenvmapmask is used. [todo tested in ?]

Error:Doesn't work in

Garry's Mod. [todo tested in ?]

$phongexponent(en) and $phongexponent2(en) <integer(en)>

A global exponent value. Overrides an exponent mask if present.

$phongexponent2 is for WorldVertexTransition's second material in

CS:GO rama de motor.

$phongexponenttexture(en) <texture(en)>

Shader(s): VertexLitGeneric

A per-texel exponent map. In an exponent map:

Red channel: Exponent mask (size of highlight, 0-255, where a value of 0 is a large highlight, 255 small.)
Green channel: Albedo tint mask (only if $phongalbedotint 1, 0-255, where a value of 0 is no tint, 255 full tint.)
Blue channel: Nothing.
Alpha channel: $rimlight mask (only if $rimmask 1.)

Nota:LightmappedGeneric and WorldVertexTransition do not have support for $phongexponenttexture. You must use $phongexponent instead.

$phongexponentfactor(en) <float(en)> (only in

)

Shader(s): VertexLitGeneric

Multiply the exponent from the $phongexponenttexture by this amount.

Consejo: The default value of this parameter is "0.0". However, a more reasonable default value would be "149.0"

$invertphongmask(en) <boolean(en)> (en todos juegos desde

)

Shader(s): VertexLitGeneric

Invert the value of the phong mask.

Error:In

s and

s Shadercode, using this parameter will invert the mask used for $envmap, not the one used for $phong! [todo tested in ?]

Confirmar: Is this the case for all branches?

$forcephong(en) <boolean(en)> (en todos juegos desde

)

Shader(s): VertexLitGeneric

Force phong shading on phong-using materials even at low GPU levels when mat_phong is disabled.

$diffuseexp(en) <float(en)> (only in

)

Shader(s): VertexLitGeneric, Infected

Diffuse exponent used for dynamic lights only.

Nota:have this with $halflambert greatly decrease it effect.

$shinyblood(en) <integer(en)> (only in

)

Shader(s): VertexLitGeneric, Infected

Derive phong mask from areas that are more red than others. Only when variation is disabled.

$shinybloodexponent(en) <integer(en)> (only in

)

Shader(s): VertexLitGeneric, Infected

Exponent for the above.

Brillo

$phongboost(en) <float(en)>

Shader(s): VertexLitGeneric, LightmappedGeneric((only in

))

Phong brightness factor. Larger values create a more intense highlight, useful for surfaces like metal and glass.

$phongfresnelranges(en) <matrix(en)>

Shader(s): VertexLitGeneric, LightmappedGeneric((only in

))

See Phong Fresnel ranges. Default is "[0 0.5 1]".

Nota:$envmap is also affected by these fresnel ranges if both it and Phong are enabled in a material.

Nota: drives the x component of a phongwarptexture if specified.

$phongdisablehalflambert(en) <boolean(en)> (en todos juegos desde

) (también en

,

)

Shader(s): VertexLitGeneric

Disables forced half-lambertian(en) shading on Phong materials.

Nota:This parameter is effectively forced on in

CS:GO rama de motor due to $halflambert being disabled.

Colores

$phongalbedotint(en) <boolean(en)> (en todos juegos desde

)

Shader(s): VertexLitGeneric

Tints the phong reflection by the color of the $basetexture. The amount of tint is defined by the green channel of $phongexponenttexture. A $phongexponenttexture must be specified in order for $phongalbedotint to work.

Aviso:$phongalbedotint cannot be used with $phongtint. The later will disable the effect.

Nota:$phongalbedotint works by multiplying the $basetexture over the reflection, without darkening the albedo. The reflection will get dimmer as a result, so account for this in the phong mask or with $phongboost.

Nota:$phongalbedotint will tint highlights by the original color of the $basetexture even when the material is tinted by $color2 or rendercolor.

$phongalbedoboost(en) <float(en)> (en todos juegos desde

) (también en

)

Shader(s): VertexLitGeneric

Phong albedo overbrightening factor. Ranges 0-255.

Nota: This will multiply the tint that is being applied to phong from $phongalbedotint.

Error: This does not work when using $detail(en). [todo tested in ?]

The Hunter without and with its $phongwarptexture, showing how it affects the Phong reflection.

$phongtint(en) <RGB(en) matrix(en)> (en todos juegos desde

)

Shader(s): VertexLitGeneric

Color tint of the phong reflection.

Aviso:This will override $phongalbedotint if both are used.

Nota: Also tints $rimlight

Breakdown of the $phongwarptexture: computed coordinates, texture and result

$phongwarptexture(en) <texture(en)> (en todos juegos desde

)

Shader(s): VertexLitGeneric

Used to create an iridescence effect, as seen on Episode Two's Hunters(en).

The highlight is multiplied with a texture. The coordinates of the sampled pixel are as follows:

x: 1 - (distance to the center of the highlight)

y: 1 - (fresnel component as computed by Phong Fresnel ranges)

Nota:Disables the initial phongfresnelranges masking

Error:Does not work in

Left 4 Dead 2. [todo tested in ?]

Brush phong in

Counter-Strike: Global Offensive using tile/hr_t/inferno/tile_a. Note the complete absence of the reflection in the shaded area.

Parámetros de sombreado de sólidos (only in )(también en )

$phongmaskcontrastbrightness(en) and $phongmaskcontrastbrightness2(en) <vector2(en)>

Shader(s): LightmappedGeneric, WorldVertexTransition

The first value controls the contrast level between light and dark areas in the mask, and the second value controls the overall brightness.

$phongmaskcontrastbrightness2 is for WorldVertexTransition's second material.

Pendiente: Find out the range of both values.

$phongamount(en) and $phongamount2(en) <vector4(en)>

Shader(s): LightmappedGeneric, WorldVertexTransition

The first 3 values control the color tint, and the fourth value controls the brightness. The fourth value can go beyond 1, but affects the brightness of the whole texture, not just the highlight.

$phongamount2 is for WorldVertexTransition's second material.

$phongbasetint(en) and $phongbasetint2(en) <float(en)>

Shader(s): LightmappedGeneric, WorldVertexTransition

Allows the $basetexture and/or $basetexture2 to tint the color of the Phong highlight.

Comandos de consola
