Hair Random Color 毛发随机颜色

Introduction

引言

This utility texture node allows you to randomize a color for each hair strand. It should be used to add subtle variation to hair color and in doing so help give it a more 'natural' look. For example this can be useful when, in conjunction with a gradient shader, you want to randomize the tip color of the hair.

这个实用的纹理节点允许您随机为每个发丝的颜色。它应该被用来添加微妙的变化，头发的颜色，这样做有助于给它一个更自然的外观。例如，当与渐变着色器一起使用时，您希望使头发的尖端颜色随机化，这种方法就很有用。

Color

颜色

This is the base color that is to be randomized.

这是要随机分配的基本颜色。

Randomization

随机化

Hue Amount

色相量

This is a value between 0 and 1 and will blend in a random hue color. A value of 0 means no hue color will be applied and a value of 1 means a fully random hue color will be applied. Values in between will create a more subtle color shift.

这是一个介于0和1之间的值，并且将混合一个随机的色调颜色。值为0意味着没有色调颜色将被应用，值为1意味着一个完全随机的色调颜色将被应用。两者之间的值会产生更微妙的颜色变化。

Saturation Amount

饱和量

This is a value between 0 and 1 and will blend in a random amount of saturation. A value of 0 means no random saturation and a value of 1 means full random saturation. Values in between will create a more subtle saturation shift.

这是一个介于0和1之间的值，并将随机混合在一个饱和度的数量。一个值0意味着没有随机饱和度和一个值1意味着完全随机饱和度。两者之间的值会产生更微妙的饱和度变化。

Value Amount

价值金额

This is a value between 0 and 1 and will blend in a random amount of brightness. A value of 0 means no random brightness and a value of 1 means full random brightness. Values in between will create a more subtle brightness shift.

这是一个介于0和1之间的值，并且会随机调整亮度。值0表示没有随机亮度，值1表示完全随机亮度。两者之间的值会产生更微妙的亮度变化。

Hair Random Color Example

头发随机颜色的例子


The example above shows a head of hair with a gradient shader applied to the internal reflection color. The gradient shader has two knots – the base color being a fixed brownish color, and the tip color being textured by a hair random color node. The Hue Amount is cranked up to 1, to demonstrate the effect. 上面的例子显示了一个头发与梯度着色应用到内部反射颜色。渐变着色器有两个结-基本颜色是一个固定的棕色颜色，和尖端颜色纹理的头发随机颜色节点。为了演示效果，色相量被调高到1	Above demonstrates the random Saturation. See how some gray has appeared in the hair? 上图显示了随机的饱和度。看到头发中出现了一些灰色了吗？	Above demonstrates the random Value, which has a more subtle effect in this example, due to the presence of self shadowing that already makes the hair look 'noisy'. 上面展示了随机值，在这个例子中有一个更微妙的效果，由于自阴影的存在，已经使头发看起来‘嘈杂’
