How to create Chrome Material怎样创建铬材质

Chrome is one of the most used materials in the Design field. This material needs only a few settings to be rendered in an optimal way. You can see many samples of chrome in the design gallery of the Florence Design Academy

铬在设计领域是经常被用到的材质之一，使用优化的方法你只需要做很少的设置就可以表现出这种材质质感，你可以在Florence Design Academy的设计画廊里面看到很多使用的铬材质的例子。Florence Design Academy的地址是
Let’s begin我们开始:

1.) You need a dark gray diffuse color (for a perfect mirror it should be black, but often a dark grey color has a better effect on chrome).

1.)你需要一个深灰色的漫反射颜色（如果是表现xx的镜像效果使用黑色会比较好，但在表现铬材质的时候{zh0}还是使用深灰色）

2.) Now go to add glossiness and specular level (there are no fixed values, the correct effect is strongly depending by the light that you create. You can begin with the value 40 in both slots).

2.)现在添加光泽度和高光级别（没有固定不变的参数，正确的效果很大程度上取决于你创建的灯光，你可以把两个参数都设置为40作为初始值）

3.) Go to maps and assign to the REFLECTION map “RAYTRACE”. This will allow you to
have REAL reflections of other objects in the scene on this material. The value in the reflection slot should be between 85 and 100 (a mirror must have 100).

Very often you need to have a environment which reflects on your object to achieve a good rendering. A good reflection will give a touch of realism to your object and will describe better organic shapes. But what if we don’t have any other object in the scene that can reflect on our model?

3.)在贴图卷展览为反射贴图通道赋予一张“光线追踪”贴图。这样可以让你的材质获得真正的能够反射场景里面 其他物体的功能。反射强度设置在85到100之间（xx镜像是100）。通常为了获得较好的渲染效果，你需要为物体添加一个环境来获得较好的反射效果。好 的反射会为你的物体带来真实感并且能够较好的表现形体的轮廓。但是假如在场景里面我们没有任何可以反射到你的物体上的东西应该怎么办呢？

We will use a FAKE reflection. This kind of technique simulates to have a environment reflected on surfaces which in reality does not exist in your scene. In fact we will use a simple image to create a Fake reflection.

我们将使用模拟的反射效果，这种方法假装使用了一个在场景里面并不是真正存在的反射环境，实际上我们将使用一张简单的图片来创建这种假的反射效果。

After you have insert RAYTRACE in the reflection map you will see that the material editor is showing new settings. This are the settings of the raytrace panel (on the right side of the material editor you can see written RAYTRACE instead of standard). Like on the image below go to assign to the NONE button in BACKGROUND a BITMAP.

当你为反射贴图通道添加了光线追踪贴图后，你会发现材质编辑器显示出新的设置。这是光线追踪的设置面板（在材质编辑器的右边你会发现光线追踪的名字已经替换掉了原来的标准材质）。在背景栏的NONE按钮上添加一张位图。
