Zh/$phong

冯氏着色器为爱莉克斯的皮肤、发带和嘴唇提供了高光。

Template:Shaderparam 它提供低强度的 漫反射 和顶点强度的 镜面高光，由控制每个纹素强度的纹理遮罩。有关完整解释，请参见 冯氏材质。

注意:LightmappedGeneric 和 WorldVertexTransition 的冯氏着色功能只在 CS：GO 引擎分支 中可用。It requires the material to be lit by the sunlight from a env_cascade_light entity to work properly and uses the dynamic shadows generated by it as a mask on top of the traditional phong masking.

注意:在 Mapbase中也提供了 LightmappedGeneric 的冯氏着色功能，但实现方式有所不同。

语法

$phong <bool>

注意:All parameters in the following example must be specified in the material, otherwise Phong shading won't show up at all, except in Insurgency.

待完善: Other games that don't require all phong parameters present (likely Portal 2 and up)

VertexLitGeneric

	$phong 1

	$bumpmap				[贴图]
	$phongexponent			5			// either/or
	$phongexponenttexture	[贴图]	// either/or
	$phongboost				1.0
	$phongfresnelranges		"[0 0.5 1]"
}

警告: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.
